First, a few words about the host. We're new to AirBnB, so we've had interactions with only three hosts and Konstantinos is by far the best -- he's a super nice guy, very friendly and responds almost instantaneously.
Now, the apartment. It's a cozy little place in a great location. Just 50 meters from the water front. You can see the battleship from the balcony! From the apartment you have a very leisurely walk of about 3 kilometers to the White Tower Lefkos Pyrgos. This is perhaps one of the best places in Thessaloniki to take a stroll. We even saw dolphins on 21st of November. Let me repeat that -- we saw dolphins in the middle of November! Another half a kilometer and you are at Aristotelous square. This is the beating heart of the city. All the shops on Tsimiski, all the tavernas in Ladadika, all the cafes on the boardwalk, they are all within a very relaxing 40 minute walk from the apartment. EDIT: Forgot to mention that the apartment has very good and reliable wifi connection, which is not shared with other guests, so it's great if you have to do remote office work.
Konstantinos has furnished the place with an oven, a washing machine, vacuum cleaner and an iron. There are all kinds of detergents and fabric softeners too!
Now, the only two downsides are these: the fridge is a bit noisy, and the apartment could get a bit dark on cloudy days. But neither of these is serious enough.
In conclusion, a great host and a clean, cozy place.
