My biggest positives are that Nasos is a great host and the location is very close to many things! Nasos was very attentive to us and was very quick to respond. We were within very close walking distance to most of the attractions of Athens.
The biggest drawback was the building that the unit was located in. The unit itself was clean, modern, and well-taken care of. The building, however, was not what I was expecting. I travel frequently and stay many different places and usually I don’t get any weird feelings about anywhere I stay, but I was confronted with broken windows, peeling paint, scuffed and chipped floors, and poorly lit hallways. I initially thought we were in the wrong place and the building was abandoned. That being said, we had an easy check in and were happy with the room.
