Solid location. Not too far from Großer Tiergarten and across the street from the metro station. This was basically like staying at a hotel, but a little better experience than usual. Room was clean and supplied with lots of coffee and other extra snacks. They have storage lockers if you arrive before check-in as I did. I had a minor issue with opening one of those lockers, but someone arrived literally in under a minute and quickly addressed the issue. Check-in and check-out were very simple and efficient. All in all, no complaints!
