I would definitely recommend staying at Dimitris place. He was a very caring host, meeting us late at night and showing us around the place. He also gave us nice welcome snacks and had many drinks stocked in our fridge and the fridge on the roof deck for our free consumption. You can tell that he has a love of hosting people. After having stayed in Airbnbs around, the world he recently opened his own here in Athens. The space was custom designed for Airbnbers and is brand new and very modern. He had great wifi, TV, strong AC, very secure with sophisticated key card access, a washing machine, a nice rooftop deck (not much of a view, but nice to sit at in the evening), and he checked in with us to make sure everything was going smoothly each day. Finally, the location is exactly what most tourists want. It is steps away from the Acropolis, the Acropolis metro station, and the Acropolis museum. We very easily walked everywhere while we were there since no neighborhood (like Syntagma or Monistiraki) or site was more than 1 mile away. Thanks Dimitris!
