I stayed at Tatiana and Philimon's with three more girlfriends.
Philimon was very welcoming, friendly, and made an effort to make our stay as comfortable as possible.
The house is modern and spacious, full of natural light, a well equipped kitchen and 24/7 hot water.
It has a small and nice balcony on the second floor which we enjoyed a lot, the master bedroom hasn't got a door though, for those seeking for privacy.
The location was excellent -a quiet and pleasant neighborhood near the historical area , just minutes walk from the city center, transportation and all of Athens main sights.
Philimon was very responsive and helpful through our whole staying and so was Tatiana previously to our visit.
Overall we had a great time.
