Helen's place is very modern, clean and cozy. It provides everything one needs - Wi-Fi, cable, Netflix, AC, fully equipped kitchen, etc. We were really touched by how thoughtful the host was to leave some food (croissants, olives, dry meats, etc.) and drinks (wine, beer, Ouzo, etc.) for us. Helen is a great host and if you need a place in downtown Thessaloniki you should definitely book it.
