Andrei's place is great. It's in a quiet neighborhood, so you'll get a good night's sleep. Also, it has a view of Thessaloniki's East Wall monument so it's quite a window treat, and it is clean, simplistic and spacious. The place is situated some 15 mins away from the city center, but if you don't want to walk the bus stop is literally across the building. Finally, the communication was great, Andrei and his girlfriend were very helpful and I wholeheartedly recommend a stay at their place!
