We have booked the appartment for a 3-day-Atens-visit as a family (1 son, 11 years old). The desciption and the pictures describe the appartment very well. The communication and service for check in was excellent. Nasos even arranged a direct shuttle service from the airport to the appartment and back to the airport for a very fair price. We would recommend this as the appartment is a little tricky to find if you are going there the first time (one way streets, dead end steets etc.). But with the shuttle it was perfect.
The location is absolutely perfect. You are in the ideal position to explore all the historic places in Athens without any need for a car.
The appartment itself was supercool an is bigger then the pictures show. The stone walls create a nice atmosphere. Everything was superclean and the appartment had everything we needed. The WLAN was working good. So we cannot complain.
There is only one point to critize: The apartment is on ground level and people passing by only in a few metres. So if the windows are open for fresh air you can be easily disturbed at night. But this is only a small critics. We would book the appartment again and also definitely recommend it!
