Nasos welcomed us very well, and came to get us at the subway station. Everything in the apartment was prepared for our stay (maps, some food...). The studio is very well located: close to the Acropolis, the museums, restaurants and bars...
It is very functional as well. It does not have a kitchen though (no cooktop or microwave oven) so it is not possible to prepare a hot homecooked meal.

I recommend it!
