I traveled to Germany to do a track event at the Nurburgring and Rennhotel was the perfect place to stay for my trip. The building is literally a block away from all of the motorsport business facilities at the Ring, and maybe 300 meters from the paddock. It is so close that it is extremely easy to come back to the hotel between on-track sessions. It was quiet during my stay as most of the track day participants stayed in Nurburg itself.
The hotel itself was very, very clean. The included breakfast was a welcome surprise of assorted fresh breads, eggs, sausage, sandwich meats, juice, and coffee. If you need an early start, at 7 am Rennhotel has you covered.
The proprietor was very kinda and spoke perfect English and was very helpful. For those traveling from big distances, just make sure you contact them about your arrival time, because they don't have someone at the front desk 24 hours a day. At night the door is locked and can only be opened with a room key.
