The stay at Olga's place was great! The apartment was clean, in a great location and communicating with Olga for check-in was very easy. We took taxis directly from the apartment to many of the sites in Athens and the longest trip was only 12 minutes. The only complaint I have is that the internet is a bit slow when multiple devices are connected, but I still give the place 5 stars overall. If I ever come back to Athens, I will definitely stay again!
