We've had a great time while staying at Konstantinos' place. The apartment is fully equipped with all amenities a family needs. It's spacious, with an excellent layout of the rooms, that makes staying there a great experience.
The place was extra clean, and we'd gladly stay there again when visiting Thessaloniki.
Konstantinos was an excellent host. He's really easy to talk to, helped us out during check-in, and was available during our entire stay (quickly responded to all questions we had).
