We visited Thessaloniki during a long weekend and were very happy with Giannis' apartment. It looked quite like the pictures and the bed is firm and comfortable (which is not always the case with Airbnb offerings). Giannis was a helpful and welcoming host, greeting us with fresh fruit, wine and some greek pastries. He even made some sorbet for us which was really nice. He gave us a good overview of the cities and lots of helpful tipps. If you are in Thessaloniki, I highly recommend staying at Giannis' place.
