Katerina was just amasing person to communicate to - she responded my e-mails immediately.
That was very good choice. Location is great - you are in the very center of the city, yet as it is a side street no noise inside.
Most of the shops, tavernas, market are in a walking distance.
The apartment is very clean, neat and spacy for 8 people. Very well equipped, including cofe, milk, honey for your breakfast. But if you are going to cook yourself there is not enough pots.
Aĺl in all it was very good place for us during our short visit to Thessaloniki.
