Firstly, Christiana is a fantastic host. She is helpful and always very quick to respond to any queries you may have, nothing is too much trouble. The apartment itself is lovely. Very well equipped, very clean and the check in process was easy. The apartment is a good location for exploring the city either by foot or by tram. We enjoyed visiting not only the Christmas markets, but also the Natural History Museum and the Spanish Riding School. Great host and a unique apartment. Would highly recommend.
