The place is nice and clean, it is exactly as you see in the pictures. You can find there everything you might need for the stay: several towels for each person, a hair dryer, shower gels and shampoos, some coffee and tea, biscuits, even an iron, etc. Good stable wi-fi (we were working from the flat). Just note that 1) it's dark in the flat all the time as it is only one window in the living room, 2) it gets rather chilly inside at times (beginning of May).
We were looking for a flat specifically in this area, so the location was perfect for us. A lot of coffee shops, bakeries, restaurants and supermarkets nearby. And in general it is a nice and safe area of the city. But if it was our first time in Thessaloniki, I would probably consider booking something closer to the city center.
The host Inessa is helpful and quick to respond, she sends clear instructions, and check-in \ check-out were very easy.
