Markus was a great host—helpful with directions and even allowed for a late check-in. The room is HUGE, especially for one person. There's plenty of space to unpack and hang your things, not to mention a lovely terrace. The bed is very comfortable and the bathroom—just a short walk down the hall—is also large and very clean. The apartment itself is well-located and about a 10-minute walk from the S-Bahn and very close to the trams and U-Bahn. I wish had more time in Berlin so that I could really make use of the space and the Friedrichshain neighborhood in general. There's so much to see and do in Berlin, I was on the go for most of my stay. Next time!
