The apartment and the host are both great. John waited for us outside even though we arrived very late. He was very patient and answered all our questions and is a very nice guy to chat with.
The apartment is very nicely decorated, clean and even has " smart-home" features.
It is 10 min walk from the Acropolis museum and in a nice neighberhood with trendy bars.
To sum up: the best placeto stay in Athens!
