Communication was excellent and Nikolaos could not have been more helpful.
Access to the apartment was straight forward and the location was safe and really close to the acropolis- I walked there one morning. It is also a good location for others parts of Athens such as the Plaka.
The apparent is small, as described, which was great for me, and I used it as a base for sleeping really. There is a kitchen and it is all very doable for two as long as you know it is quite compact - which is my experience of most places in capital cities. Great value for money.
Air Con and shutters were both invaluable!
I had a great stay and would highly recommend.
