Stefan's flat was spacious and airy, with more than enough space for the four of us, and is in a great location for the centre of the city. There is a climb of 126 steps to get to the apartment, so if mobility is a problem this isn't the best place to stay, but we thought the flat was worth the climb. We used the sofa bed and the extra matress and found them comfortable, and the flat was very well equipped - there was even some Austrian coffee for us to try. Stefan was a brilliant host. He was very responsive to messages before arrival, helped us carry our bags up the stairs, and gave us a great list of recommendations for local sights. We would love to stay here again.
