We had a terrible experience with this place.
Top Management is poor. The apartment is very small and lacks of proper furniture. There are not cleaning products, and when asked the told us they cannot lend us. We stayed for two months. Can you imagine two months without proper cleaning equipments?
The sofa and bed are terrible. You will have back pain for weeks. Often they asked us if we are staying there. They don't have a clue who is staying and who is leaving.
The A/C filter smells terrible. I believe it needs to be changed and some maintenance.
We brought a pillow with us and the pillow was missing after the cleaning service did a 'refreshment' of the place. They offered from the lack of equipments. The cleaning was terrible, the mop was smelling like wet dog.
The street is very dirty and smells bad, full of garbage in the street.
I wouldn't recommend this place, and also if you go to Thessaloniki as a tourist or as a digital nomad, don't stay for too long.
