There are quite a few guesthouses dotted in the area around Nurburg and Adenau. They offer Motorsport lovers superior accommodation, some have workshops, garages and memorabilia filled rooms.
Pistenklaus is the Mecca for a Motorsport. The most popular restaurant as it is filled with memorabilia, has a range of unmissable hot stone meals and is owned by the family of Sabine Schmidt, the renowned unofficial ambassador of the ring. Its recommended to make a bee line for the restaurant as soon as you arrive to make a booking as it is busy all throughout the season
If you want to spend a bit more and have the 4 star hotel experience I recommend the Dorint Am Nürburgring. Although this is part of the chain their hotel is motorsport themed. They have lots of memorabilia dotted around the hotel.
