Ana and Nikolas are great hosts. They were friendly and fun to talk to (in German, English, and Spanish). They had good recommendations about what to see and how to get around Berlin. The room is very comfortable with a desk and storage and a comfortable bed. The apartment is small (by US standards) but it has everything I would ever want while traveling including a washing machine and a balcony. The location felt very safe (honestly, all of Berlin felt safe as long as you didn’t walk in the bike lanes!). Within three blocks there are probably at least a dozen restaurants/cafes/take away places, plus a REWE (grocery store). It’s also within a block of several tram lines (5-10 minutes to main train station) and the underground so all of Berlin is easily accessible (Tip: Citymapper made Berlin transit very easy to navigate. Also if you’re going to sightsee in Berlin for a few days, a transit pass like the Berlin Welcome Card makes it even easier).
