Nikos's place is a very lovely 1-bedroom apartment on the 5th floor of a residential building. It has everything you need and a balcony. The streets around the area are parking controlled Monday to Saturday so you either need to pay or park 10-15 minutes walking distance away if you arrive by car.
All and all I had a very pleasant and good value stay. I will use Nikos place next time I find myself in Thessaloniki.
