This is a fantastic place to stay in Vienna. Martin met up with us outside of the apartment within a reasonable time and introduced us to the flat. There were excellent amenities, including water, milk, little snacks, little shampoo/conditioner/body wash tubes and it was really a nice surprise.
Location was good, it was located right by a grocery store and within a 5 min walk of a U-Bahn stop. It is also within I nice part of town (I think. All of Vienna seemed like a nice part of town). If you didn’t want to take the U-Bahn, walking to attractions was not that bad.
