I stayed Antonis' apartment almost 3 weeks, and during my stay contacted with both Antonis and his sister, mostly. They were very helpfull to me. If you have heavy luggages like me, it will be a bit difficult to reach to the apartment from bus stop at the beginning:) however, the location is perfect,you can find whatever you want around the building.the city center is very near,you will not need to take a bus or any other vecihle. Moreover, the area is safe enough for walking. Most of the main attractions of Thessaloniki can be seen by walking. Also, historical place on the top of the city named Ano Poli could be reached via walking if you trust your breath:) otherwise, the bus option is also avaliable near Antonis' apartment. Many Thanks for Christinia and Antonis for their help and hospitality.
