We had a great time at Konstantino's place. It's in the center of Thessaloniki. Easy to find, also thanks to the good explanation of Konstantinos himself. He made us feel very welcome in Thessaloniki and his appartment. He gave us some good advises about restaurants and areas. The appartment was very clean and big enough for the 2 of us. If we ever come back to Thessaloniki we would definitely book this again.
