I didn't have any hot water to take a shower for most of my stay. I wasted a lot of time communicating with the hosts to get it fixed. They responded with repetitive stock responses, completely forgot previous conversations we had, said a repair person was coming when they weren't, said it was fixed when it wasn't, and refused to address my requests to receive a discount as a result of this.
The room was fine but no hot shower during a cold January in Vienna was a big inconvenience, and their service and communication was friendly on the surface, but uniquely awful in substance.
Highly dissatisfied, not at all recommended. Strongly suggest to avoid.
