The apartment building was well located in a quiet neighbourhood, but with easy access to U-bahn and S-bahn stations. Both less than 10 minutes walk away.
As a mature woman travelling alone, I valued the security aspect of the apartment's situation.
There were, however, a couple of down sides.
The Wi-Fi was extremely poor.
My particular apartment had all the eating and kitchen items on shelves set high above the kitchen bench. Being only a couple of inches over 5 foot, they were impossible to reach without climbing on a kitchen chair. If you are my height or under, maybe check out that the apartment you are booking does not have this configuration.
