It was a perfect stay by Anastasios, the flat had everything we needed and he knows well how to run this as a host. It was a pity that we didn't have the opportunity to meet, but he put in place for us an easy way to give the keys and some notes + a map on the table with instructions on how to reach interesting points of the city and sourroundings.
The flat is in the center of Athens, making it really easy to visit, and being located at 8th floor the view from the balcony on the Acropolis is just amazing!
