this is a wonderful place to stay in an amazing city.
we had six here comfortably (including 4 teenagers). the kitchen is well-stocked.
this is in a very nice building (with an elevator and AC) in a nice area of the city. the beds were comfortable and the showers great.
i am anxious to get back to vienna and will definitely stay here again.
the staff was wonderful and helpful -- allowed us to leave our bags after we checked out.
if you are going this summer, there is an exhibit at the albertina modern of ai wei wei's work over his career which is fantastic.
