We arrived a bit earlier than check-in time and used the self check-in process which worked perfectly. We expected to leave our luggage but found the unit already cleaned and ready so we went straight in. This is a nice option to be able to get into the unit without having to contact the host(s). The detailed instructions were appreciated. The unit is just as described in the photos and the loft bed is very cosy. Also, it was quite warm outside and the unit kept relatively cool considering the 35 degree Celsius weather. 2 minute walk up to a street full of shops, restaurants and the subway. 20 minute walk to the centre of old town and maybe 25 minutes to schonbrunn palace, though we took the subway back which we realized was simple and convenient when it was too hot to walk. Overall a great little place to find refuge between your activities in Vienna.
