I stayed one month in Thessaloniki and this flat was the best choice I could make. Walking from here to the city center in 10 to 20 min, an astonishing view, the flat so nice and cozy you can feel like beeing home - even when you far away from it.
I had my car with me, and I loved to chaotic way of Greeks driving. From here, it takes only some miniútues to reach the ring road to Halkidiki, Olympus ...everywhere. It es a very good starting point for all activities with a car - and per foot in Thessaloniki.
The whole area is part of the old city, very steep, lovely old buildings, very nice restaurants on top of the hill (near the wall, about 10 min walk).
You have everything you need for a short or even a long stay. The only thing is that you have to take good care of the plants outside, especially in summer. So for a weekend trip to somewhere else, watering the plants well is a must. Which I did with pleasure, since Konstantin is a very caring, very respectful host. Everytime I will be in Thessaloniki, I will try to stay here. For me, it was just perfect.
