My short stay in Athens was made effortless and enjoyable thanks to Dimitris's friendliness, immediate responses, and of course his wonderful apartment.
The apartment was very easy to find, just a couple minutes walk from Attiki Metro station, which connects to everywhere I wanted to go (for example, it's just a few stops to the Acropolis). The ride was so short from the city center that I didn't mind popping back to the apartment in the middle of the day to drop some stuff off, barely losing any time. The place was clean, roomy, and has a beautiful rooftop space for relaxing and enjoying the sunset. The air conditioning was a lifesaver after full days walking around in the hot sun.
The wifi was fast and the bookshelf was well-stocked with guide books and other random fiction--a nice touch to make me feel at home.
I have absolutely no complaints. This was a truly excellent trip, in large part thanks to Dimitris and his awesome apartment.
