It was a good place to stay, Holger and Jenny are very friendly. We were in the basement, the kitchen is great, you just have to know that the two bedrooms are linked, you have to go through the first one if you want to go in the bedroom in the back, it wasn't a problem for us. The shower and the laundry are in the basement too, so it helps to have good relationships with your roommates (upstairs) if you don't want noise late at night.
Near the house you have bus stops, the subway and the train. The neighborhood is calm and quiet. Documentation is provided to help you if you want to discover the city.
