This is a lovely apartment very centrally situated near Friedrichsbahnhof. 3 of us stayed, a couple and another adult - we had loads of space and would easily accommodate more. Very quiet in spite of proximity to the station. The balcony seated us all comfortably and is like another room, with a view over the courtyard below. Currently scaffolding on the adjacent courtyard wall but we didn't find the work intrusive.There are many restaurants within walking distance. Not air-conditioned but still nice and cool in hot weather. Easy handover of keys with Martina's friend, good communication meant our flight delay didn't cause any issues (at least for us!)
