This place is a great little stay for the single traveler or perhaps a couple. The building is very central, in an adorable area, and the security is excellent. Make sure to take some time to walk around the area, there are a ton of little cafes, restaurants, and Christmas markets this time of year.
At first I was a bit overwhelmed by the check in process, but as I examined it closer it was only because the level of detail was so thorough. There are 3 separate entry landings to get into the apartment, and each one is thoughtfully designed with automatic lights and secure access points. Once I was in the apartment the local tips and WiFi were also a straight forward and helpful.
