Great space for my husband and my needs on our 3-day trip to Vienna. Check-in was flawless, Nina was easy / prompt in her communication, and when we ran into some trouble with the wi-fi -- she and her husband came over right away to solve the problem (which ended up being a sim card issue) and they went out immediately to have the company fix it and it was there by our return that evening!
The furnishings / space is comfortable for two people (a little on the smaller side but when you're on vacation, it doesn't matter much since you don't spend that much time in the apartment) and has a mini fridge to stow leftovers and drinks, as well as cutlery, plates, cups - which came in a lot of handy one evening when we decided to order take out instead of dining in a restaurant with a long wait.
