The Penthouse was the best part of this trip! There's an elevator in the building which takes you to the 6th floor so you only have to climb one flight of stairs. The bed is so comfortable, I want one of my own. The space was stylish, comfortable, and welcoming. We didn't want to leave! We were very jet-lagged when we got in, but Tom was very helpful with check-in and check-out was very easy. There are a lot of good restaurants within walking distance, and a train station nearby which makes it easy to get around. Definitely will stay here next time I'm in Berlin! Thanks again :)
