We loved staying a Marleen's place for a week in October. The apartment is pretty much just a advertised, a pretty good sized main room that encompasses the kitchen and sitting area, then a small bedroom and bathroom. It's pretty much perfect for a couple, but beyond that I could see it being crowded. Marleen was a good and helpful host. There is a cafe just downstairs that's open late for drinks, which is very convenient.
I would highly recommend getting to know the public transportation system ahead of time. Tram 3 stops right in front of the apartment around every 10 minutes, and you can get just about anywhere in the city very easily. The neighborhood is outside of the touristy section, so we had no problems with noise. We would return here in a heartbeat.
