Viktoria's apartment was comfortable, well designed (just as seen in the photos on the listing) and in a convenient location. The self-check-in was easy (thanks to clear instructions sent ahead of time) and worked very smoothly. We also appreciated the flexibility, as we arrived late in the evening. The apartment is within less than a 5 minutes walk from the U-bahn station, and a comfortable 20 minute walk to main attractions such as the museum quartier. All in all we had a very nice stay. We were only there for 5 nights, but the place is well equipped (kitchen and laundry), and could probably work for longer stays as well.
