The apartment is very lovely. It is beautifully renovated and they have pretty much thought of everything and it's done vey tastefully.
It's in a convenient location, very close to the U Bahn station (only a few minutes to all the main parts of the city) and about a block and a half walk to a great street with lots of cafes, shops, supermarket etc.
Picking up the key was a bit tricky, but once we sorted that out everything went very smoothly and the host was easy to contact, and there to answer any questions.
Even though it is located on a busy street it wasn't too bad noise wise in the apartment.
