We were a couple on a trip to Berlin, and had a great experience. We received quick info from our host prior to arrival, and met with Cata who waited for us at the apartment when we arrived - a very kind and friendly reception. Quick communication!
The neighborhood is great! Used to live in Berlin, and the area around kollwitzplatz is full of nice restaurants, cafes, pubs and shops. Recommend Anna Blume for breakfast or lunch.
The apartment was clean, large and with much space for two people, but you could easily be one more as there is a sleeping couch. Kitchen was nice. Can only recommend this!
