Very nice apartment, with a fantastic view from a penthouse above and at an excellent location!
We were a company of 7 girls and had a great time there! Although the building is very old and looks ugly from outside, the apartment is renovated and with a modern decoration.
It is spacious (although slightly smaller than it looks at the photos) and it can accommodate 7-8 people, since the sofa becomes a double bed (it is comfortable).
The photos showing a balcony are not from the main apartment, but from a penthouse above (separate door), that was for our use too.
The owner is very polite - he even let us check-in earlier in a rainy day - and responds instantly.
We only has some minor issues with the cleanness (coffee machines, under the sofa, etc.), but I am sure that the owner will fix them. Also we could not operate 2 of the air-conditions, but he was very eager to help us with that (finally we did not insist us we did not need them at the end).
The locations is perfect. Very close to Acropolis metro station, Acropolis museum and Dionisiou Aeropagitou street. There is a city super market across the street, and some mini markets around it. Also, it is located at the area of Koukaki, where many restaurants and bars have opened the last years.
So, I would recommend it for a company of friends that want to do some sightseeing and also discover the nightlife of Athens.
