My husband and I stayed here only for 2 nights mainly to attend a ballet. Be aware it takes about 30-45 minutes from here to get to city center where most of the sightseeing is. It is very near a UBahn station though. The location was great for us - literally a block from the ballet. We were able to find good food and coffee all around in this location. Comfortable enough for 2 - couch and large TV w/HDMI hookup, kitchen table with a pretty well-stocked kitchen for making coffee/tea or if you want to cook some basic food. Everything was automated for check-in which I preferred because I hate waiting around for people to let me in the building (especially when its raining or cold). Thomas was reachable by phone and very helpful when we did have a question. My only complaint is the bed - horribly uncomfortable and extremely loud - just from turning over in my sleep it would wake me up. Otherwise, we were comfortable during our stay. I wouldnt recommend this to anyone who is more interested in spending most of their time in the center of Berlin, but if you have things to do in Charlottenburg, go for it.
