The flat is big and looks really like the pictures so no surprises! Stamatis is really nice and give many advices about what to visit or where to go in Athens. Whatever you would like to do, eat, drink, dance, visit, he has an address for you and is happy to share ! He was really helpful and he reply quickly to messages so it is very convenient to organize our arrival or departure.
The pool is also great, especially at night, it's amazingly beautiful.
Maybe the negative point would be that if you have noisy neighbors... You'll hear noise coming from the stair cage :(. But that's not too bad. The whole stay was great !
