Thanos was a wonderful host. He was extremely prompt and helpful in answering my questions and provided a great check-in with food and drink (and coffee!) to set me up in the apartment. The apartment itself is lovely--very clean and a comfortable space in which to study and relax. It's also an easy 15-minute walk to Evangelismos metro station, and there are plenty of bus stops even closer to the apartment that can take you to the centre or elsewhere in the city. The neighbourhood is safe and quiet and has its own personality. I would recommend the apartment for anyone staying in Athens, short or long term--it's a great place to be based!
