We missed a ferry due to a port strike and needed a place to stay for a couple days. Mark and his family were great and made us feel welcomed from the start. The best feature about this place is the patio, which is HUGE -- and what a view!
This is a residential area so not much to do or see in the immediate area but you are a 20 minute walk to the Acropolis and just about anything else you'd want to do. There are plenty of bars, restaurants, and dance clubs within that 20 minute walk. Personally, I preferred the Keramikós district (10 minute walk). Any travelers in their 20s or 30s who like a more casual music club would feel welcome and at home there. If you prefer dressier establishments I would recommend the Gazi district, which is a 10-15 minute walk.
Enjoy!
