We had a nice stay at the apartment and liked the quick communication of Robert!
The location of the apartment was ideal with the (almost) free parking place in the street (weekend) and the public transport nearby (it's very clean and punctual). Also the park Augarten nearby was really pretty!
The code to come in was perfect so you already can't lose the key 😉
The van was a nice extra because it was really hot when we are in Wien.
The studio is compact but big enough.
