We stayed for 4 weeks and we could not ask for a better stay. My only note for future guests is that it is located in an area with many sirens due to hospital and police station, but very safe area because of it. Host was super accommodating and attentive, as he is located in the same building during office hours, and was quick to address any issues (which were rare). We will definitely look to stay here again if/when we return to Athens as it is directly on top of the metro station, (only 5-7min from Syntagma) and there are many non touristy restaurantsu in the area that are priced very well (for locals).
