-Super clean.
-Great location. 2 minutes from Keramikos underground. Personally I walked to Akropolis, Syntagma and Monastiraki.
-Food and bar options close by.
-Easy self check in/out. I checked in at 2am after a later flight, Nasos sent me a video showing where the key lockbox is located and what keys to use to unlock the building.
-Secured building. The flat is on the 3rd floor and you have to go through 3 doors (bldg has elevator). Very private too.
-Great host. Nasos will check on you if you need anything and he replies quick if you have any questions.
I would definitely recommend this place!
