This hotel was booked for us by my host at the Max Planck Institute in Old Golm (now incorporated into Potsdam) and is essentially a country inn. Many of those we saw at breakfast were group bicyclers touring the area, and there are numerous scenic sights to see if one has a bicycle or car in this western suburb of Potsdam. Of course, Potsdam is also famous for Sansouci, inclusive of palace and extensive gardens.
While internet was not free, it was not expensive. The service was exemplified by a knock on our door at 8pm our first night, when the desk attendant presented us with our missing roll-a-boards, that at last were delivered by Air France after failing to put them on our flight to Berlin.
The room was above average in area, very clean and comfortable, and the hotel also provided an adequate breakfast. The bar and restaurant also were nice, and we found both lunch and dinner there to be pleasant and enjoyable.
The hotel is close to bus stops that make accessing the main railway/bus station in Potsdam easy, and the Golm train station is almost as close by foot, and goes directly to the newer Berlin airport (Schoenefeld, SXF) in 28 minutes.More
