We were a family of four and the apartment was perfect in every way for us. It's a few minutes walk from Monastiraki Square and all the main sights. The check-in was easy with a pin code and Nikolaos had left clear instructions about the apartment in a notebook. He also provided snacks and juice, which was helpful as we arrived late from a long ferry ride on Sunday night and were too tired to go eat. The sleeping space in the living room is a little loud because of the surrounding rooftop bars, but fine with earplugs. The trade off is that everything is nearby and we never walked more than 20 minutes in any direction to reach restaurants and sights. Would highly recommend!
