The flat was very clean and tidy, and perfect for an overnight stay with our two young (7 and 4) kids. It is perfectly located between an S and U bahn, and the city centre is within 15 minutes.
Martin was very helpful with prompt answers to our questions before we arrived, and also let us into the flat earlier than the normal check-in time, for which we are grateful.
The kitchenette was not really for cooking, but we knew that beforehand, but was perfectly suitable for our short stay. Like everything in the flat, it was new and clean, so no complaints at all.
Overall, a very positive experience. Thanks Martin!
