We rented this house for 7 days on our trip to Berlin there was 10 of us and the house was big enough for all of us
The house is soundproof so we didn't cause any disturbance to the neiborhood
The sauna was an amazing addition and very enjoyable
The heating is great inside the house
We had a problem with the plumbing at the downstairs bathroom but the problem was almost imidietly solved in less than an hour as Patric our host was quick to act
Overall we had a pleasant stay and we recommend it to big groups of friends that want a vacation
