The appartment is nicely decorated and equipped with everything needed even for a longer stay. There is a spacious terrace which is very pleasant to sit at, although there's no parasol which would be of great use, as the sun can be very strong. The kitchen is equipped with basic ammenities such as salt, sugar or coffee. In the neighbourhod there are lot of stores, bakeries, cafe's etc. It is easy to access the bus for the City centre, or airport. The appartment is on the fourth floor, and there's no elevator which is an important informations for elderly and families with small kids. Also, the bathroom is pretty small which could bother less agile people.
Kalliniki was an excellent host. She responded quickly, and even let us enter the appartment earlier then scheduled.
All in all I would recommend it, and would consider it for a next stay at Thessaloniki.
