We had a very pleasant stay in Alexandra's loft, in the center of Thessaloniki, just 1 minute walk from Aristotelous square. The loft has everything you may need and is clean and warm even with closed air conditioning. Alexandra was willing to help us with the earlier check in and is offering free of charge lockers to leave the suitcases after the checkout till you leave the town. Plus, she asked several times if everything is fine and shared her personal favourite spots in town!
I surely recommend her lofts!
