The apartment is great for couple. Everything was very clean. It is well equipped - it has a hair dryer, flat iron, coffee maker and pods, smart TV, mini speaker etc. The bed is extremely comfortable. The apartment is in an excellent location for visiting all the sights of Thessaloniki. We visited most of them by walking. There are restaurants and fast foods in the immediate vicinity.
Maria and Nikos are very helpful, polite and friendly hosts. Communication was great from booking to check out.
The only challenge we had was finding parking on the street on Friday next to accomodation, which is expected in a bigger city and in the center. Anyhow, there are a lot of space in parking garages. Keep in mind that the garages are mostly closed on Sundays, because parking on the street is free from 4pm on Saturday until Monday morning.
Altogether I recommend K suit for comfort, location, cleanliness and friendly hosts.
