The house itself is placed within a short walk from the town center. From there it is very easy to get on the S-Bahn to Berlin. I highly recommend buying a Welcome Berlin ticket for your entire familiy if your plan is to visit Berlin daily like we did.
Gaby came with all kinds of advice and suggestions in advance of our stay there. That helped us a lot , and in the end saved us for a lot of planning.
The house is very nice both on the outside and the inside. It is very easy to feel just like home when you relax in the evening after a long and interesting day in Berlin. Especially the beds are worth mentioning. Rarely are the beds so wonderful to sleep in like those at Gaby's. Too many time have we seen and felt the opposite in a rental house.
Highly recommended.
