Absolutely good place. Very good location near biggest museum and absolute good walking distance from core touristic center. If you are a walker, almost all attractions in the whole city are reachable. Apartment is adequately equipped but since restaurants are so cheap, I did not end up cooking much. Check in was convenient and host pardoned me arriving a day later (i did not count the +1 day of my travel).
Super market close by and host provided a whole book of what is in the neibourghood and things to do in Athens. 8 mins from Omonia square and all convenience.
Good tv with 20+ channels. Provides good value for the price. Makes hotel prices look ridiculously high.
And the place is quiet, which is good since Athens streets are so noisy.
