We loved staying at Stamatis's place. Its super spacious for two people and keeps nice and cool even in the Athens heat. The surrounding area is fascinating! Has lots of cafes and bars that I wish we got to explore more.
The apartment and pool is a little more worn than the pictures show but it's still great value and it was amazing being able to use the pool on the roof when we wanted. We had dinner up there one night which I would recommend doing.
Location is great too.
Would definitely stay here again.
