The GOOD: the flat is private, in a fantastic location, and a very good price. We felt secure and safe. The host was very gracious and eager to attend where he could. The tram is less than a block. Minutes to anywhere in Vienna. Close to great eateries. Easy to find
SHOULD KNOW BEFORE BOOKING: There are a few details that will help you make your decision. First is the bed. It is a very hard sofa that folds into a “bed.” It made it very difficult to sleep (unless you like very hard beds). Second, the toilet is old and thus can not accommodate flushing toilet paper. It may not bother you, but it is something to consider (the paper goes in the trash next to the toilet). Not saying these are good or bad, but it will manage expectations when you arrive. I didn’t mind the toilet at all— my partner did.
Overall, we thought it was a good space, a good price and good host.
