I travelled two months for work to Athens and staying for the two months at Konstantinos place was the most comfortable solution. The apartment is really cosy and nice. It’s located in a great area, and if you want to stay for long period it’s ideal as it’s connected by two main train stations (Petralona and Syngrou). And the best part is that you are super close to the Acropolis and the centre by foot.
Konstantinos is an excelente host, always very friendly, flexible and extremely helpful with everything I needed. Totally recommend the place!
