Although we didn't meet Andrea, her partner, Daniel was an excellent, communicative host. This included allowing us to use their washing machine. The flat is in the basement of a modern, three story house in a newish suburban housing development. The living room has floor to ceiling windows, however ( so lots of light) and there's a terrace outside with a table and chairs. The flat is quite large and spectacularly well equipped with a very comfortable large bed and an excellent bathroom. Importantly for those who are light sleepers, It is TOTALLY QUIET. We stayed for three nights/four days and there was no sound either from the exterior or interior of the building. Parking is easy if you're travelling by car.
There are a few restaurants close to the property (Italian, Chinese etc), but the closest bars are a short bus ride away. In spite of its suburban location, public transport gets you to the heart of the old city (eg. Marienplatz) in around 20 minutes. As you'd expect in Germany, public transport is highly reliable and frequent.
Andrea and Daniel's flat is an excellent place to stay for a few days (or longer) and comes highly recommended.
