Great apartment in the heart of Vienna- would stay again. Hosts were incredibly responsive, we booked last minute and they responded quickly and accommodated a morning check in so we never had to tote our luggage around the city. I would advise that the sofa bed is very firm and very small- I am 5’3” (160cm) and I did not fit on the fold out. Ended up just sleeping on the couch itself (my father took the bed), which was large and comfortable. I also did not note any air conditioning, but the building is cool and there were two fans and we remained very comfortable.
