Great hosts, great room and location.
Issues:
Noise - id suggest bringng earplugs. The room is facing a pretty busy street. When I moved in there was also a construction going on outside.
The internet. The host owns the two floors and unfortunetly the router is situatated in the floor below. This means the connectivity can be sometimes shady. If the people renting the apartment from below are heavy users of internet you will feel it too.
