The tiny and nice apartment has everything you need. Everything was clean and the access to the roof it was awesome. You can enjoy the view on the city and harbour.
Moreover the apartment is located very central so that you can reach everything very easy by feet.
In addition Stefanos gave us so much tips about sightseeing and some spots next to the city (beach etc.). If you want to visit Thessaloniki, you can be happy if you are hosted by Stefanos!
