We had a short but good time in Rio's appartment (only one night). Unfortunately we didn't meet him but met his wife who was really helpful to show us the area and the appartment.
Thanks a lot for the tavern indication near the studio, we had a great meal there, cheap and tasty indeed!
The studio looks exactly as described and furniture look new, bed is confortable.
Well located, near metro station and Acropolis museum (10min by walk) but be warned that you will have to climb stairs to reach the place. May not be recommended for old people or if you have lot of luggage.
