Helias's studio is perfectly located, just 5 minutes from Thessaloniki's beautiful promenade. There are frequent buses into the centre (Aristotelous Square), and you can also walk if you like. The studio itself is small. However, for one person it's all you need. I spent 1 month there while in the city and it was absolutely fine. The neighbours can be a little noisy, however I think this is common in most parts of Thessaloniki and Athens. Helias himself is a fantastic host. He is quick to answer any questions and is always there if you need anything. It was a pleasure to stay at his place.
