Excellent place! Daniel was very welcoming and helped us settle into the Thiseio area. He gave us some great suggestions as to where we should go and what we should do. He also rescued us from our taxi driver!
It is really close to two metro stations and is within minutes of the main sights in Athens, as well as very close to the nightclubs in Gazi.
The apartment was clean, well-decorated, the furnishings were up-to-date, and the kitchen was well-appointed, with everything from a panini press and a french press to assorted pots, pans and other utensils that made cooking meals an easy task in the apartment.
