This is a simple budget hotel. Location can not be beat and neither can the value. It is tucked away in a little square in between the Plaka pedestrian area and a transportation corridor on the other side. Very quiet at night and some rooms have nice view. Rooms are simple but clean, breakfast is also simple but sufficient. Athens has expensive hotels and I felt this was exactly what we expected and needed for the price we paid. Internet signal is a bit weak on the higher floors but in the lobby it is fine. Short walk to the Acropolis and the Museum. We even walked to the Lykavittos Hill to watch sun set behind the Acropolis. If all you need is a clean bed for the night and clean shower, this is perfect choice.

Good room for the price and great location. I spent 4 nights in the best Plaka location walking distance from Acropolis and Sintagma, in a quiet room with balcony and plenty of space. WIFI available in the room and premises. It makes you feel you are in a Greek home. Very kind management, they even served breakfast at 5:30 a.m. the day we were leaving.
Only a little problem: hot water not available all the time.
I'll go back if in Athens. Thanks to Matt Barrett for his advice: www.greecetravel.com

We stayed at the adams for just 1 night , we were given a room on the second floor.
The room ,a double, had a small but functional bathroom and a small balcony,facing one of the sidestreets.

The hotel is basic but was in the perfect location for 24 hours in athens, right in betwen the acropolis, syntagma square and the plaka district.Also about 5 minutes from the Acropolis metro stop.

Walking tot he acropolis took maybe 7 minutes an the lose location allowed us to reach there well before the large groups, and thus avoid the queues, also near to the hotel there are loads of fod and drinks options , as well as shopping and souvenir shopping.

For the price i paid,80 euros, with very short notice i was satisfied with what we got, by no means was it a 'beautiful' hotel, but it was functional and clean, which is all we needed.

This hotel is right at the Plaka, where I would recommend staying when visiting Athens. The Plaka is full of restaurants and small shops.
The hotel is in walking distance from all the historical sites, the acropolis, the olimpic stadium, etc. It is also very close to a metro station, we took the metro from the airport and walked to the hotel with our luggage, no problem.
The hotel is old and a bit dated, but it was clean. The room was small, and so was the bathroom, but again, it was clean, so it was perfect just to sleep there, we spent the day outside anyway.
