We had a really nice stay - the apartment is located in the center of Thessaloniki, just some minutes walking to the White Tower. The communication and check-in was always fast and without problems. We even got a second pair of keys when we requested it. However, it was quite cold when we were there in January and the air-condition doesn't heat the place up so well - so that could be improved. Plus, the furniture is also rather old-fashioned as the description says and therefore the big bed in the sleeping room is creaking a lot. But that's just two downsides from an overall nice experience. If you are looking for a place that is really downtown to spend some nice days in Thessaloniki it's definitely recommended!
