If you are looking for a place to stay for two in Vienna, this is the one you need.
It takes a couple of minutes to walk to the city centre, it has a few good supermarkets (Billa and Spar) close-by, it has all the necessities + more, it has the best pizza place in Vienne right around the corner, the entry and the windows of the place are facing a very tidy/quiet alley and the hosts are kind, helpful, have good tips for things to do in the area and have excellent communication skills.
My friend and I have been here before and the experience with Katerina and the place were, once again, perfect. We both highly recommend this stay!
(If you need to park your car, it is recommended to do so in P+R Spittelau, it is super cheap, well-guarded and easy to access. You can Uber your way to the stay or take a 20-30 minute walk next to the flowing rivers going through Vienna)
