Frank's apartment is great, really stylish and with everything you need. Super clean and just 1 min walk from a station so easy to get anywhere in the city and from the airport. Also, super quite although close to a main street with everything you might need. It was the perfect place. The only slightly issue we had was the low wifi connection but with so many cool things to do in Berlin we didn't really spend much time inside. I definitely recommend it and would stay there. Thank you Frank.
