My wife and I stayed in the Hotel Deutsches Haus for one night in May 2010 after visiting the Volkswagen Autostadt in the nearby Wolfsburg. The place was clean, had ample parking space (we came by car) and lies in walking distance of downtown Gifhorn. The hotel offers a quite fast Wifi internet (@ € 5 per hour) and given that the rate we paid for a double room included a nice breakfast buffet the next morning the price was okay. The only downside was the for our taste too soft matresses...
