We really enjoyed our stay at Petroula&Giannis apartment. I must say that this is the most stylish airbnb apartment I have ever been. Really super chick decor. Also it has all you need for your stay in Athens. It is close to Petralona metro station. But I must warn you, Athens are very up and down the hill, so get ready to shape your body :) The hosts were very helpful and both with a great energy.
