My son and I stayed there for two nights in September after we realized that the whole town of Ingolstadt is fully booked because of some Audi event. The first night we stayed at NH Ambassador paying 150 euros for two, without breakfast. The other two nights we spent at this hotel spending 84 euros a night including breakfast, which is a good deal.
It is a 15 minute drive by car from the city center (use GPS), or a quick trip by train (platform is within a walk). It is a small and very quiet Bavarian village with friendly and hard working people really trying to please you. The rooms are quite basic, but clean and after renovation. The best part of it is the restaurant downstairs (the main feature) where food is tasty and affordable. We may stay there again, if come to Ingolstadt by car. More
