To echo previous reviews, Sarmad is an excellent host. Very quick to respond & very flexible.
The apartment is very spacious & clean. It is sparsely furnished & lacks a bit of refinement but is comfortable for a short stay. The location is great with easy transport links but only a 20 minute walk to the centre of Vienna. We enjoyed local restaurants and the film/food festival at the Rathauspark.
Vienna is a stunning city!
