We loved staying in Christos apartment, it was exactly like the photos, really nice and comfortable with everything that you might need. Mrs Christos met us and was very helpful with tips on what to see and do.
The apartment was clean and we felt very at home.
There are shops and some restaurants close to the apartment and you get a feel for how the locals live as it's not right in the main touristy part of Athens, but still close enough, a 5 to 10 minute walk to the tube station and 2 stops to the Monastariki area. I can definitely recommend it, you will enjoy your stay.
