Flat very close to the center, maybe not the best neighbourhood, but didn’t feel worried or scared for a minute. Flat also big, with many beds and all the necessary things someone might need. Some food shops around and 24 hour mini shop for snacks etc.
Kiki is great, very pleasant, helpful and quick with the responses.
I highly recommend this flat and I will definitely go back to it when back in Thessaloniki. Thanks Kiki.
