Purpose of stay: visit Vienna, stayed for 2 nights.
About Host: very friendly, fast communication, also flexible when it comes to arrival and departure time. It went all smooth.
About Accommodation: relatively basic. I had the feeling the cleaning lady was slightly too quick doing her job (but this may be subjective). As expected, the flat is already in used-up condition.
Since the bed was somehow broken, i had a miserable first night. The host reacted quickly and fixed the bed for the second night, it was good then. However, the bed does not have any legs (different on the photos), so basically you are sleeping right above the floor.
I was surprised that the shower was half broken so one needs a few more minutes in the bathroom. Maybe, by the time you will arrive, it will be fixed.
Location: you are in the middle of vienna, great location. You can walk by foot everywhere.
