Klaus is an excellent host, very flexible and accomodating. He communicated promptly and reliably, which is great when you are travelling to arrive somewhere in a big city. He bought initial supplies for us and carried our bag up stairs ! The apartment is in a great location, right in the heart of Barcelona, yet the rooms are set away from the street and therefore very quiet. The apartment is very characterful and authentic, the lift is just like in those old movies. It is spacious and well equipped. Klaus leaves loads of recommendations for sightseeing and dining out, and all his recommendations were excellent. Thanks for making our trip to Barcelona so special Klaus, best wishes Robert.
