Zarah's place was fantastic! The location is great, so easy to get to lots of S/U-bahn stops and lots in the area. It's an easy walk to Prenzlauerberg and a long but not bad walk all the way to Alexanderplatz. We walked up to Babel for falafel a couple times! Zarah's place is easy to get to, check-in and out is extremely easy. The bed is comfortable and more American-style than many Berlin spots. The shower is great, although the tub is deep so if you are short or have issues with deep steps, beware, as it is a big step out. Hot water was great, too. No A/C of course but the doors/windows open and we got plenty of cool air, even on warm days, and it gets pretty quiet after 11pm or so. We also loved having access to a washer/dryer, although beware that there's only two, so don't save it for last minute in case they're both full! Zarah was very communicative and helpful.
