I can HIGHLY recommend staying at Kosta's apartment! The area is as good as it gets - many restaurants and bars, the harbor and the famous shopping streets while you can walk (almost) everywhere within 10-15 minutes. The communication with Kostas was great and easy, he made our stay unforgettable and I am very happy we got to meet in person. The A/C was great to come home too with up to 40 degrees outside (July/August). When back in Thessaloniki we will definitly try to rent the same apartment again. Thank you Kostas & Solomon!!
