my stay at stefan's listing was fantastic. the apartment is extremely well located. you are close enough from the museums and the various other destinations (theater, opera, Heldenplatz, parks) without being immediately in the fray (the apartment is a ~5-10 minute walk from the aforementioned spots). the apartment is very quite and peaceful and offers maybe one of the best beds i've ever slept in. the large fridge and wonderful porch were very welcome as well. very recommended and i will definitely try to rebook this listing if i ever have the opportunity to visit vienna again!
