First of all: We had a wonderful stay in Stelios apartment in Thessaloniki!
The location and other information were accurate and the apartment was very clean when we arrived. The towels and the bedlinen were just fresh washed!
Due to the fact that we stayed in december, there were also heaters so we had no problems with the cold.
Also the Check-in was very easy and the communication with Stelios was perfect. He answered very fast and gave very nice advises about the city and recommended lovely places.
There are a lot of supermarkets and restaurants in the close area which you can reach in less that five minutes walking. Also the city center is very close, maybe 15 minutes by walk and watching a little bit around.
All in all we can only recommend this apartment and especially Stelios as the host :)
