Everything was great, the apartment was extremely large, and the staff were so friendly with us and our duaghter. Apartment Locations is fantastic, you can reach most of the famous places in 10 minutes, like Piccadilly, oxford, Hyde Park and new bond street. Cleaning every two or three days, which is more than enough, and you can ask if you need any towels or anything anytime. It's looks like a family house, and they treat you like you are one of them, not a customer.

I was actually planning to give the hotel 9 of 10 because the elevator was not working on the last five days of my stay because I was on the fourth floor, but because of the young lady (sorry I forget her name, she was on recipient when I checked out today) I will diffenatilly give them 100 if I can. She insist to help me to carry 8 big luggages (32 kg) each from the fourth floor using the stairs, she took 4 and I took the rest (I'm sorry and I hope you didn't hurt) thanks again and I'm sorry I forgot your name

The apartment was really big, clean and comfortable. Compared to hotels in the same area it's a bargain. We will definitely be returning, but next time with the kids, it's a great jumping off space. There is a good lift to all floors (not a scary one 😂). The bed was amazing! There was an air conditioning unit in the room which worked amazingly on a very warm July night. The concierge was really helpful and let us check in an hour early (we were at a wedding, so this really helped with our times), the concierge is between 10am and 6pm on weekends. It's in a great location!

The car parking was slightly difficult- it's a reverse down a thin back lane to an underground car park, the car was also locked in between 6 and 10am, which meant we couldn't leave as early as we would have liked.

From the moment we booked we received fabulous service. Late self check in was organised as our flight arrived after reception hours. Our apartment was beautifully appointed, stylish and so comfortable. There were even Christmas decorations to mark the season. The staff were so friendly and helpful. The area immediately around had a host of options for dining and a quick drink. The apartment was so close to our favourite shops including Fortnum & Masons and Hatchard’s; and Buckingham Palace was just a 10 minute walk away. We look forward to a return visit soon.

The flat is huge (for central London), beautifully decorated, very comfortable, extremely well equipped (including Nespresso machine) and very clean. High ceilings, lovely art work and seriously plush sofas add to the luxury feel. Very good wifi. The location in the heart of Mayfair is excellent, with local shops, restaurants and bars. Many sights are within walking distance, including the West End. Green Park tube is only a 5 minute walk, and buses even closer.

The bathroom is large but a little dated and could do with an upgrade and a separate shower instead of an over-the-bath one. The flat is very quiet, except there was loud music one night until 4.00am from one the other flats. We spoke to the host the next morning and it didn't happen again. Although the wifi is very good, there are no streaming services on the TV - Netflix or similar would be good.

The apartment was spacious, quiet, well decorated with a huge and comfy bed. Lots of lovely and thoughtful amenities were included in the kitchen and bathroom. The location is fantastic for exploring London - Mayfair is beautiful with cool Shepherd's Market right on the doorstep; and the rest of London, east and west is easily accessible by tube. Lots of great cafés, bars and eateries within walking distance. Staying at 9 Hertford St presents considerably better value than staying in most central London hotels - room to spread out, self cater, be close to everything, and be able to rest and relax.

The fittings and fixtures in the rooms are a little bit dated but fully functional. There was also minimal lighting throughout the living room and bedroom. Very limited "in room" information is provided regarding whether there will be any cleaning or servicing during your stay and also there were no instructions on how to use appliances like the washing machine. All of these things were very minor and would not stop us highly recommending 9 Hertford St as an excellent place to stay.

The property is centrally located in London and at same time, located in a quiet area. Wonderful staff. Full furnished 1 bedroom apartment with all the necessities for your stay. Spacious and nicely decorated. Comfortable king bed. Two good coffee shops close by and several excellent pubs and restaurants within a couple of blocks. Plenty of transportation options nearby. Walking distance to several tourist attractions. Bus, train and taxis readily available.

This is one of the best properties we’ve stayed in. There’s nothing to dislike. You might make a different selection if you wanted to closer to Piccadilly Circus, Chinatown, or the West End Theaters but we were happier in Mayfair.

The apartments are very well located - an easy walk to Harrods, Buckingham Palace, Regent and Oxford Streets, Hyde Park and Green Park as well as tube stations. There are pubs and a variety of restaurants close by. The apartment was very comfortable and spacious and the staff were very helpful. The kitchen had everything we needed for our 6 night stay.

The location was excellent for getting around London and lots of fabulous places to eat and enjoy a beverage right outside the door. Easy to access public transport or just walk to many parts of London, Buckingham Palace, Hyde Park and Harrods. Very convenient to have a washing machine and lots of room to relax after a long day out and about exploring. Easy access with a lift or stairs. It was lovely to have a balcony and get fresh air.

The apartment could have a bit of refresh / uplift.

The apartment is lovely. Bed was comfortable with plenty of pillows. The apartment was large with lots of closet space. The reception staff was wonderful. I have an autistic daughter who can be a bit chatty and the staff were very kind and patient with her. The parking garage was a challenge to find, but the lovely gentleman on reception was very patient and helpful. We only stay in London a few times a year but may go more often thanks to finding this gem.

The parking garage was very difficult to find.

Location is perfect, 10 mins walk to the palace and gardens, just a few mins to Hyde park. We loved the decor and comfort as well as safety and quietness. Front desk staff very helpful.

The sliding doors to the balcony are way too hard to move. They eventually do move with some weight behind it but this needs looking at. It is a bit pricey but central London generally is and it is difficult to get location, size and comfort all in one package for a reasonable price so you just bite the bullet. Front desk staff not overly knowledgeable about the area.
