We stayed here in June 2015 and quite enjoyed it. Our room was huge, though the bed was too soft for my wife. She was perfectly comfortable sleeping on the couch. We loved the Charlottenburg location: just a few minutes from Ubahn and Sbahn stations and many shopping locations. We started our two weeks in Germany here for a few reasons: close to the airport, easy access to Ubahn, good prices, and an electronics store nearby to get new chips for our phones. Lots of good shopping in the area. I had tremendous fun wandering around the area with my cameras and found several very good restaurants while my wife slept and recovered from our long flight over.
We quite liked the breakfasts, they were an excellent way to fuel up and start the day.
I would not hesitate to stay here again if I ever get the opportunity to return to Berlin, which I greatly desire. My only negative thing to say is a personal problem: I have some lung damage, and I'm sensitive to cigarette smoke, and if you have that problem you'll sometimes smell it in the hallways. Also, as of when we were there, the only WiFi was in the lobby on a very old computer. I would suggest buying a very big data plan for your smart phone and using Yelp and Google Maps a lot. read more
