We really enjoyed our stay in Berlin. The place was spacious and equipped with everything we needed.
Great location, easy access to anywhere in the city via the nearby u-bahn and tram stops. Nice coffee shop right downstairs. Also, like many apartments in Berlin, this was built around a nice quiet courtyard - which creates a wonderful sense of "escape" from the busy street right outside.
Check-in was easy - Matt was ready for us at the pre-specified arrival time, and very helpful at getting us oriented. We had one minor issue come up and Marcus responded within minutes to help us resolve the problem. One last thing we appreciated was that there were plenty of spare linens/towels and the in-unit washer/dryer - both very helpful when traveling with a family!
