The word for this place is only one: perfect. Perfect place to go around the city and easily catch the taxi to the airport too. She keeps her place as comfortable and also prepared some extra equipment for my requests: the drying machine and softener. And she provided me a lot of information for the city, so I could bring warmed clothes in terrible snowing white season; actually that is so rarely cold during my staying.
Anyway I recommend this place to everyone planning for travelling to Thessaloniki.
