I had a really enjoyable stay in Thessaloniki. The apartment is very well situated (less than 5 min walk to the White Tower and about a 10 min walk to the main square). The apartment is very clean and modern, and had everything I needed. The check-in and check-out process was very efficient and well documented and Helias was a great host to deal with. He was very friendly and attentive in our communications so I wouldn't hesitate in recommending either the apartment or Helias to any future travellers. Overall, a lovely apartment in a great city!
