Aris was a great host to us !
He arranged a great taxi driver to pick us up from the airport and hand-over of the keys in spite of the late arrival. He was always fast to reply to any inquiries that we had.
The flat is a great base to explore Athens, as it lies in Psyrri with a walking distance to brunch places, convenience stores, bars, restaurants and sights.
The highlight is definitely the view of the Acropolis and Aris arranged for us that we could watch the fireworks on the Acropolis from the roof top terrace in that house.
The flat was clean and equipped with many things (even a laundry machine) and looked exactly as on the pictures.
Small negative for those visiting during colder times: as it was so could outside, the flat did not get very warm (despite the extra mobile radiator), so we cuddled up a bit more.
All in all, I can highly recommend Aris place for your explorations of Athens!
