The flat is in a very nice part of Berlin with good cafes outside and conveniently close to Bellevue station on the Bahn.
The two main rooms are spacious with plenty of daylight. Kitchen and bathroom are modern and tidy.
The flat was advertised with two double beds and a camp bed. In fact there was just one bed and it felt like a single. Fortunately my wife and I are not large people, yet we found it very difficult to sleep.
The shower curtain was a few cm short of the bath so every morning we had a lot of water on the floor.
The other vital part that was missing was a bottle opener/corkscrew.
