Frank is a super nice host, he was waiting for me when I arrived, he gave me some really cool adresses for shopping. He booked me taxi and everything for my departure... The host you dream of...
The hotel is really cool, I really liked all the details of the avant guardist design: art, 80's cinema, music and life seems to inspire Franck.
Everything clean, you can help yourself with everything. Kreuzberg is a large neighbourhood, I didn't go so much time to visit, I only went to a rock liveband show at Comet Club, which is 5 minutes from the hotel. There is a Bio Company supermarket at the corner of the street, where you can find fresh and healthy food.
Awsome staying! I will come back and advice Franck's place to my friends!
