Vasilis is a great host, offering great flexibility to coordinate checkin and checkout. He clearly explained all what's necessary to know about the place and offer help for whatever is needed.
The location was in a great location, slightly noisy till late evening due to the bars located right down the apartment, but the place has perfect isolation so it did not bother me at all.
It has a nice modern style, very pleasant. I stayed alone for a business trip, yet it hosts perfectly two people. All in all a highly recommended place to stay right in the old center of Thessaloniki.
