Henning and Ariane's home was the perfect choice for our long-term rental. We stayed in their home for a couple months as we were looking for a permanent residence.
Their home is very comfortable, clean, quiet, and in a beautiful location. With two large bedrooms, a spacious living room area, and an in-house sauna, the home was all [and more] of what we could of asked for. Since we were staying long term, a cleaning service was provided that kept the rental fresh and light. The surrounding area is a beautiful and quiet suburb [however, quite easy to take public transit to downtown Berlin] with some great restaurants [Rhodos and Il Mulino were exceptional], stores, markets, and parks [make sure to see The Grunewald] nearby.
Coming from the US with limited knowledge about the area and German-speaking skills, Henning and Ariane always went out of their way to assist us. They helped us with general questions about Berlin, coordinating mail, and helping us get acclimated to the city. They were very attentive and caring hosts which made our stay very comfortable.
In short, their place comes with high recommendations - whether for a long or short term rental.
