I spent five days in this very nice stylish apartment. Christina is a nice lady who takes great care of her apartment and goes out of her way to make one feel welcome! Her apartment is very comfortable, fully furnished and has a large balcony.
I never heard any noise from neighbors. There is outside noise from traffic, but this is a common problem in Athens or Thessaloniki. I did not want to bother with mobile wifi and went right next door to a cafe to use wifi. Christina was very nice and left her job to help me with the apartment wifi, but I just did not have the patience to use it properly.
This apartment is located right on the bus lines to take you the center, to the airport (2 buses, E 1 each) and to Halkidiki (2 buses, E1 and E4.50+). It's a great value to use it to visit Thessaloniki and Christina' amazing hospitality (bread, fruits, jam, supplies) made my stay even nicer!
