The property itself is close to the Athens museum and the Acropolis, restaurants, cafes and generally most eateries. Also, close to the main road where you could hop on a sightseeing bus. A brisk 5-10 min walk to Plaka and Monastiraki.
Our room was spacious, with a kitchen and a walk in robe with plenty of space to hang your clothes. Finally, the bathroom was decent too.
There is also the option to have your breakfast delivered to your door. The downside was that by the time it got to you, it wasn't very warm.
The room we had didn't have much of a view but I'm not sure about the other rooms.
The one negative was trying to get our luggage up a flight of stairs. There was an elevator for luggage, but we were on the first floor and and didn't need to use it.
Overall, a good experience.
