We were travelling to Vienna as a group of 5 for a week long conference and this apartment offered an excellent base for the week. It's extremely well located for the metro which we used every morning to travel to the outskirts of the city, but also was great at night time for exploring Vienna. Despite its central location, the place is quiet and calm, with plenty of space for 5 people. The sofa beds are also very comfortable. The host was extremely communicative and was very helpful with recommendations of things to do and responded very quickly when we locked ourselves out (apologies again!!) Overall, this place is excellent and we would stay again.
