Based on my previous experiences with flats in Vienna, I'd say that Hannah's place is a true gem. Located in a nice neighbourhood, with very good connections to every other part of the city and further, the flat is unusually affordable. It is nicely furbished for a short stay for two close people (I am not sure if the couch in the living room can be turned into bed for a third person). It has absolutely all the amenities you'd need on a holiday, or even for a longer stay (properly equipped kitchen, small but fully functional bathroom, gallery with a decent bed for two, and a separate living room). The neighbourhood is very quiet so you can have a good sleep even later in the morning. Hannah was very prompt with her responses on my inquires, communication was seamless, and the check-in/check-out couldn't be easier. Whenever on a budget, I'd gladly rent her apartment again.
