My partner and I stayed here for a week while we were visiting Thessaloniki.
We had a wonderful time in the city and a great experience with the apartment. It is located very centrally with good transport connections to the airport and main bus station. It is also a short walk away from a lot of nice cafes/restaurants/landmarks. It is also very close to a popular night life area which is good if you want to experience this but was quite noisy during the weekend.
The apartment was very clean, it was easy to find and check in was also really easy. We arrived quite late and were able to check in using the lock box which was really handy. The air conditioning is also very good for escaping the Greek heat.
Pau was a great host and was very helpful in answering any questions we had about the apartment and also gave lots of helpful advice about Thessaloniki.
We would both highly recommend this apartment!
