The apartment is great for long stays and for working remotely. It has fast internet and a separate desk. The kitchen is equipped with pots, utensils, cups, plates, you name it. The host is very attentive. We needed an extra key and a ladle for the kitchen and it was promptly delivered.
The bedroom was a little hot for us in August though. Also be warned that since the apartment is on the ground floor, you will hear pretty well everything that's going on outside, especially the garbage truck in the morning. :)
Apartment has great location, not far from the supermarket and a wonderful promenade along the seaside.
I highly recommend the apartment for staying in Thessaloniki and Sushan as a host.
