The appartment is 100% like described. Really cozy, equipment is really good, all necessarythings like coffee, sugar, spices, towels and toilet paper is available. The apartment is located in the center of the city and the harbour is reached within 10 minutes by feet. The airport can be reached by cab/taxi for 20€, so you don´t hae to take the bus.
As Thessaloniki is a big and crowded city, it can be a bit loud at night, so you might can´t sleep with open windows. We would really 100% recommend the apartment and stay there again.
We really enjoyed the stay, keep going like that! We wish you all the best!
