Had a terrible experience here. During our stay the boiler was broken and it was only possible to have a warm shower for 4-5 minutes once a day. The host insisted the boiler wasn't broken despite us sending them photos of the boiler gauge at cold and no red light on to indicate it was working. Eventually after going through Airbnb they replaced it with a slightly larger one - which still only had enough water for ONE 9 minute hot shower after waiting 12 hours for it to heat up! We had to wait for the plumber, and send pictures of their boiler back and forth. Trying to resolve the issue ultimately disrupted our whole holiday in Vienna. Wouldn't recommend staying here until they sort out the hot water - although even if it's fixed we won't stay again due to the host's lack of sympathy. They refused to offer any refund. Through Airbnb after sending photo evidence we managed to get a 20% refund. There are plenty of affordable, beautiful places to stay in Vienna - avoid this one!!
