Stamatis is an exceptionally outstanding host. He speaks very good English, gave us a complete overview of the apartment and gave recommendations about how to tour Athens. He helped us get a package delivered and when the delivery company had trouble delivering, he spoke to them over the phone for us.
As for the apartment, it is immaculate. It looks just like the photos -- there is no bait-and-switch going on here. It is very roomy as well -- more-so than other places we have stayed. Its location is very convenient and feels safe.
