Staying with Carmen was hands down my best airbnb experience I've had to date. The place itself is an idyllic little space, the covered front are was great to sit out and listen to the rain in. The room was very spacious and pleasantly lit, and if privacy was necessary there was a pullout couch. Carmen offered us free bikes to get around Berlin, which would have been great if not for the rain. She even let us store our luggage there while the place was cleaned from the previous tenants so we could explore the city. Truly a hidden gem :)
