Very clean, modern, must’ve been recently renovated. The beds were SO comfortable-not the typical European style they had a mattress topper and my goodness I slept so well! Centrally located and within walking distance to almost all of the sites, if you are able to walk 20-30 minutes (great workout and early in the morning it’s splendid). Beach close by also. Breakfast far exceeded our expectations! Staff was very friendly and even gave us great recommendations for local Greek restaurants.

I thought I wouldn’t be able to sleep with the street noise and surprisingly it wasn’t a problem at all. We heard our neighbors more than we did the traffic. Honestly nothing we didn’t really like about the property. Oh, actually, I forgot about the parking. It was a bit tight and if my dad wasn’t with me I definitely wouldn’t have gotten the car in.

The staff was helpful and the room was very spacious

Because my flight touched down after midnight and had to use the the e-key, which didn't work at first, really worried me. When you arrive through international flight, having worrisome not being able to get in the room is not really pleasant. Because of everything is controlled by the card, AC turned off while I was away and it was pretty much all day because I was staying for business, it was like going back to a sauna room.

I enjoyed my stay at this hotel. It was quiet, calm, air-conditioned, with spacious rooms. The breakfast was excellent, a 10/10. It was very close to public transportation, so I didn't need to use taxis. They allowed me a late checkout until 6:00 PM for free. There is also a rooftop restaurant at the hotel (affiliated with the hotel), offering luxurious dining with a stunning view and amazing desserts. I highly recommend it!

A key via the smartphone app, a good idea, but sometimes problematic (weak internet, slow response, etc.)

the breakfast was delicious, as was the rooftop restaurant - Opposite. The dining, including the cuisine, the service and the vista was outstanding. I was so pleased with the experience the first night following a long day of travel, that I returned on my final day before my return flight. I really felt so nicely cared for by the staff throughout the hotel.

That's a hard one. The staff went out of their way to help. Initially, the location seemed a bit out of the way, but that may have been more me, needing to gain my bearings.

A wonderful hotel with an amazing view of the Acropolis! Our room was comfortable, spacious, and sparkling clean! "Alexa" was a great addition to the smart room and gave our stay an extra fun vibe! We had dinner at the hotel rooftop restaurant "opposite" where the breathtaking view was complimented by the wonderful flavors!! A must-have is the breakfast, with a variety of choices on the buffet as well as the option of the addition of warm dishes from the menu! On top of this, the staff in both the hotel and the restaurant were exceptionally polite and professional!! A wonderful stay to be repeated!!

As a new entry in Athens, i made myself and my wife a present and stayed a night in this diamond hotel! With an Acropolis view, I was more than happy with the room. It was spacious, modern, clean, comfortable and nicely furnished, with a separate lounge area. There was a balcony from both the lounge and the bedroom which overlooked the Acropolis. For anything we needed there is a smart app as a personal assistant. The staff were all very friendly and helpful, particularly in the executive lounge. There was a good selection of soft drinks and snacks and breakfast was extraordinary, including a la cart choices. I didn't have to get up or request a refill, as the staff were so attentive, they topped up or refreshed my drinks and snacks as soon as they noticed they were getting low! The hotel is located a short taxi ride from many of the sights and from popular areas with an abundance of bars and restaurants, so I would recommend going out to eat and drink. However, it is worth an evening drink on the rooftop bar, just to take in the views. Moreover, the drinks and restaurant are really value for money places to spent time in the hotel! I didn't have a chance to use the gym, or the spa area but the communal areas, bar and restaurant are modern and clean and overall I really suggest the hospitality experience. All check ins even to the elevator use are made by a simple app! Clever and comfortable...

Everything was great, the staff was very attentive and kind. The suite was spacious and super clean. We could walk to almost all sights which was convenient. The dinner on the roof terrace was wonderful and delicious.

We would not need the digital gadgets in the room. It is easier to switch on a TV with a remote control than to ask Alexa 10 times and then to call the reception :)

Its a brand new hotel. The location was great!. The food was amazing (prepared by a famous Michelin starred Chef). The rooms are actually more like luxury apts with kitchens! The roof top restaurant had unobstructed views of the Akropolis! State of the Art technology all over and the e-shop feature is innovative. The staff was very friendly and accomodating. There is Spa and Wellness facilities but I didnt have time to visit. I will definately stay at 507 for more nights at my next trip.

Parking inside the hotel was not available yet but was opening up shortly.

507 has awesome views of the Acropolis, Observatory, and Lycabettus Hill – perfect for a fancy stay. The rooms are comfy and stylish, making the whole experience even better. Self-check-in makes arriving super easy. The staff is cool and friendly, creating a welcoming vibe. It's a comfy and hospitable spot for a great stay. Don't forget to hit the rooftop restaurant for tasty traditional dishes with a modern twist and a cool wine list! 🍷

A small extension in the open hours of the restaurant to further enjoy the view of the Acropolis by night would be nice.

Very nice Hotel. Great location with great Views. Rooms very spacius, beutifull decoration. Very advanced technologically. Breakfast is great. A rich buffet with an option to choose your hot dish from a wide selection. The "benedict eggs" better than anywhere else I had them and the "kagiana" was an unexpected very Greek suprise. Not to miss the views to Acropolis and the other major landmark hills of Athens. The Opposite restaurant at the roof top not to be missed.

I wished I could have more days to stay !
