Stayed here for a total of 4 nights last week. I found this place as a "Rare find", and it truly was. It checks the box on almost every parameter:
1) Great location, just 5 mins walk from the metro (Aghios Illianos), and about a 20 min walk to the city centre which has all the attractions.
2) Clean and comfortable space, and quite spacious too (we just two of us).
and finally, the most amazing and hospitable host Dimitris. He went out of his way to help me during my stay. I had booked for a total of 4 nights, 3 nights, followed by a gap of a day and then 1 night again. My husband and I went to Santorini for 2 days in between the two stays at Dimitris'. Dimitris was kind enough to keep one of our bags for a night, in his own apartment (he lives in the same complex). He also helped arranged a taxi, a known driver who charged us the flat rate of 35 Euros at 5 AM - no uncertainty of arrival of taxi, price negotiations etc. so very convenient. And on the final night of our stay, we arrived close to midnight and requested if we could check out a bit later (the time is 11 or 12 in the afternoon I think). He was kind enough to check the arrival time of the next guest, and let us stay on until 4 PM.
I highly recommend the apartment and the host for anyone who wants a place near the city centre Athens.
