For everyone that wants to go to Thessaloniki - the apartment is the perfect place to stay! It is located in the centre of the centre of Thessaloniki and contains everything you need (even more equipment than in the description is provided). Also you have got a great host at your side that really cares about your well-being. Kostas suggested us lots of great places (typically greek). The communication with him is also very simple. The apartment is furnished with lots of small details and you can realize that someone really cares about this place (so you can not do anything but feeling comfortable).
We have been very satisfied with our choice and would recommend it to anyone. If you are still hesitating - don't! It is absolutely worth it!
