Hotel Keinath - Stuttgart, Germany 

Quite an experience! This spartan (& cheap! via Activehotels) hotel was obviously a dormitory for the Porsche factory workers. The room was simple, with a view of residential street, shared toilet and bathroom. The architecture was 60's style, as was the bathrooms. The room itself was refurbished recently. The atmosphere was special in the sense that the famed Porsche factories were situated one km away, and it was easy to imagine this three-floor dorm has been made for the workers. Don't forget to have a look at the factories, though outside the showroom I only saw two porsches driving the surrounding streets. It was strange to note that the workers seemed very common, not being in the position to buy the vehicles themselves. Btw, very friendly and unassuming receptionist.
