Unfortunately all positive things about this apartment were overshadowed with the fact that it was impossible to sleep there, as well as the attitude of the host.
Beds in both bedrooms are in a very bed condition. They squeaked loudly at every smallest movement, which meant that we could not rest properly for two nights we stayed there, as you would wake up middle of night just by turning on the other side.
When I pointed out that to the host, they suggested to cancel the booking and receive refund for the second night. This probably explains the lack of honest reviews of this place (when guests cancel you will not be able to provide a review). Cancelling was not an option for us as we were in Thessaloniki only for two nights and last thing we wanted to do over our holidays, was looking for a new place.
To the future guests I warmly suggest to contact the host beforehand and inquire if the bed issue has been fixed.
Otherwise it is in great location, spacious, tasteful renovation. Indeed the flat is well isolated from the street sounds however you hear every single noise within the apartment and also surrounding neighbors.
