Very pleasant and good value studio flat in the charming Kallithea area of Thessaloniki (the equivalent of Montmartre). Dimitrios is very friendly and helpful, was waiting for us when we arrived, and gave us excellent restaurant recommendations. It was freezing cold when we were there (close to zero degrees) but the flat stayed nice and warm. Recommended.
The only slight problem we had is that the wall attachment for the shower was broken, so you have to hold the shower head with one hand while you wash. Also the mattress may not be comfortable for more than a few nights (you can feel the springs). But this flat remains a very good value option for Thessaloniki.
