In a nutshell: my stay at Frank's place is what has completely converted me to AirBnB; that is to say it is the only way I intend to travel from now on. Frank is easily one of the most friendly and interesting people I have met through this site. His place really must be seen in person to appreciate: it is somewhat a combination of an art studio and small hotel (with 2 rooms), it has an awesome movie room/theater in the basement (projector, viewing screen, 12 seats, etc.). All of this piling onto the fact that it's located in the hippest/artsiest parts of an already incredibly hip city (think San Francisco: specifically the Mission and SoMa). If you are looking to experience the vibrant youth culture of Berlin stop your search because Frank's Pension Art is the place for you.
