Stel's apt is a really nice place. It's close to the city centre and all touristic attractions. Just next to apartment there is a supermarket. In the apartment you have everything you need for cooking (like olive oil, spicies, honey, coffee) and to relax. WiFi works perfectly so as washing machine :D Stelios is a really nice man and he gave us many helpful tips about where to go in Thessaloniki. When we're back in the city, I'm sure we'll stay at him!
