It's a very good cozy and clean apartment bang in the city centre. It is small but the space is used very well, and it is right on the main pedestrian street leading to the central square. Everything is in the walking distance, and Kostas gives a fantastic rundown of the places to see, eat and drink. I used his map with elaborate suggestions all the time I stayed in Thessaloniki. An amazing bougatsa place for breakfast is just round the corner!
