Overall good stay. Location is close to the city center, there is public transport nearby. There's everything you need provided in the apartment.
A lot of hills in the area so expect to go up and down a lot while on foot.
Heating is central, so if it's not on when you're there and weather is cold - prepare to be cold. Blankets keep you warm pretty well, but you can't lay in bed all the time...
Mattress is really soft.
