Dimitri and Alexandra's apartment was great.
Finding the location from the airport shuttle bus stop was very easy and check-in was also very smooth.
The apartment is located in the very center of Thessaloniki and I could reach almost all the sight seeing spots easily by foot. There's countless bars, cafes and restaurants just around the corner. It got quite a bit loud outside in the evenings but the window was good enough to block the majority of the noise.
The room is very clean and modern and looks exactly like in the photos. The shower and toilet in the middle of the room with a glass wall may be something you might have to get used to, especially if you travel with someone (not too much privacy there).
All in all it was a great stay. I can recommend the apartment to anyone.
