Overall great, spacious place in a quiet residential neighborhood with great views. Great value for the space and views.
Pros: Quiet, a lot of space, amazing views, walking distance to the center (10-15 minutes) or you can take the subway, everything you need as far as amenities (great washer/dryer, WiFi, coffee, great A\C, water pressure and temperature is great, etc.). If you want to climb Lycabetus Hill you are basically half way up from the apartment. Thomas is a great responsive host. The neighborhood is very good, restaurants I would say are great, especially if you want something less touristy than the city center.
Cons: It is uphill, so if you are elderly or disabled, it is quite a steep climb as you walk back from the center, though you can always take a taxi. All of the stairs are not baby friendly, though we were fine with our 2 year old.
