Frank's place was awesome, as the recent reviews suggest. It was a little pricey for Berlin (staying as one person in a shared space), but seemed to be the best option I could find on a short time frame and was very happy with it. Frank was a great host, he's ver friendly and personable and his home is a great unique experience in an amazing location. It's close to transportation, the canal, and a nice area of shops and restaurants. The neighborhood felt safe for me to walk around whenever as a young girl traveling alone. I would suggest Franks place for sure.
