We had a really enjoyable stay in Petra's guesthouse. The self-contained guesthouse was around the back of the main house which made it a little hard to find but once we got there it was great. We especially appreciated the hospitality Petra and her daughter provided, bringing us baked desserts and even a few Christmas gifts! It's a fair way out from the heart of Berlin by public transport (about 1 hour) but the town and surrounding forests are beautiful. Would definitely recommend to anyone who is easy-going and looking for a relaxed stay.
