Plus points: Superb location, comfortable beds and a lovely bathroom and welcome from our host. Downsides: noise from the other groups in the building, poor ventilation leading to a strong smell of damp, not improved by the lack of heating in the summer. Two of our group have dust mite allergies, which they said affected their sleep. Ideal for a short stay on one of the most interesting streets in Kreuzberg with friends, but felt more like glamping than an urban loft.
