I would highly recommend Sandy as a host, although I never met her, communication with her was pleasant and instantaneous and of course professional.
The room was amazing and really lovely I must add, I would love to leave in a flat like that.
Location wise the room is located in one of the most central and beautiful areas of Thessaloniki, believe me I know, it is my hometown, you are going to face a bit of a problem with parking but if you absolutely need to have a car there is a parking with not totally unreasonable prices right across the street.
Sandy was really helpful and the automated hassle free system she uses will make her my first choice next time I need to visit again.
