I stayed here with four other friends and we enjoyed it! It was 95 degrees in Athens and the AC in the apartment worked great. The place is very spacious, clean and was perfect for 5 people!
The apartment is also in a very good part of Athens and there are so many stores, restaurants and bars nearby. You are also very close to the metro station which is how we got to the air bnb.
Communication was good and they even let us check-in early. We did struggle with getting the key out of the lockbox but they were very responsive and came to help us out immediately.
Would definitely stay here again!
