My family and me stayed for 3 nights at Johnny‘s place and have to stay it was really fantastic. Johnny always responded very fast, worry informatively and kindly and was extremely supportive whenever we had questions. The place itself is spacious, nicely decorated with everything you need. There are two bath rooms (one with shower/bath tub and one without) which is perfect for families or groups of friends.
The air conditioning saved us as we stayed in the heat wave- and the apartment was always kept in a comfortable temperature.
The district is also a cool place to be at. At Victoria Square there are lots of cheap coffee places to go to, the archeological museum is only a short foot walk away and so is the city center. You can also easily take the subway. For us with kids this was the perfect option.
We can really recommend this place to stay when you are in Athens!
