Had an amazing time in Rainer's apartment. The location is fantastic has great links to airport and trains and in the best district. Rainer was very friendly and helpful. Thoroughly enjoyed my stay in such a great city. Be aware though, the apartment is up 4 floors (80 stairs) or so it can be tiring if you have lots of luggage which thankfully j didn't. The place is also above a few bars and pubs, so over the weekend it can very noisy outside. They are only minor issues however. Would love to stay again soon! Thanks rainer.
