Perfect!
If you want to enjoy Thessaloniki, this is the right place for you. It's close enough (20 minutes walk to Agia Sophia, for ex), and far enough from busy central streets (quiet, but close to all the playgrounds that are located between Hotel Makedonia Palace and Opera). Finding parking spot on the street can be a bit tricky, but not impossible like downtown. If you are coming with kids, it's perfect choice. Apartment is as shown on photos, clean and equipped with all you might need. Communication with George is easy.
