We had a fantastic stay in Kally's apartment which is quite literally a stone's throw from Aristotelous Square and couldn't be more convenient. The place is within easy walking distance of all the main attractions and located on one of the city's main arteries, making it easy to pick up a taxi or use the airport bus service which has stops right outside the door. Communication with Kally was great and check-in very smooth. The apartment is clean, characterful, spacious and very well-equipped. The road below is busy but you could barely hear it with the windows closed and the aircon is very efficient. Highly recommended for a city break in Thessaloniki.
