Great apartment from great host! Location is also perfect - the apartment is in a rather quite neighbourhood, but just minutes away from a busy street with lots of shops and restaurants. The way back to apartment is onto a very steep hill, so it might be hard to get there for some people, but it didn't cause any problems for us. There is a children's playground and outdoor excercise equipment just a minute of walk from the apartment - was very convenient for our kids to play.
The apartment has a heating boiler, so it was warm, which is good for December. The only drawback is that the boiler is in the kids room (room with 2 beds) and it is rather noisy at night. We were turning it off for the night.
The bathroom is very small, but it was enough and did the job. The other apartments in the area all seem to have small bathrooms.
The host was very responsive, solving all the small problems we've had.
All in all - great apartment, highly recommended.
