For a short stay in Vienna, I should say it was okay. Timur’s hospitality was great, he gave us a fast response and a complete information about the city.
But the thing you should note about the place is the bathroom was separated from the toilet and the bathroom size is very small, it might not be a problem for petite size human but for an obese it will quite disturbing.
The plus thing about the place is it has an elevator, so if you bring a heavy luggage it won’t be a problem
