Norbert is a an amazing guy.. such a gentleman carried my huge bag all the way up to the 3rd floor. he went out of his way to make the accommodation as comfortable for us as possible. communication was fantastic There was a misunderstanding about one of the amenities that i requested that he was originally not ok with but it showed up on the list on his apartment, and accordingly i rented the place, he was more than happy to let it go for us. I forgot something in the apartment after we left, and he actually delivered it to me!! as for the flat, it was amazing, exceeded my expectation. the location might be away from the center, and the U-bahn station is at least a 20 mnt walk, on a rainy day that could be a problem, this i would say the only thing that was an issue. as for Norbert and the flat itself, i recommend it strongly.
