I loved staying in the apartment! It was very conveniently located. It was only a short walk to the Ring where we did a lot of sightseeing. Although we did not use the public transportation (we were able to walk everywhere we wanted to go), the subway was very close by as well as Westbahnhoff train station. That was very very convenient.
I could list many more advantages to staying in Strfan's apartment, but I will suffice it to say that he was a great host. We were very comfortable, and the apartment is charming and modern. The bed is amazingly comfortable. The shower is great! It is located on a pretty quiet little street... The perfect place to come back to at the end of a long day of soaking in the city.
