Shinjuku Sharehouse is the liveliest guesthouse I've stayed in during my trip in Japan! People of all nationalities were mixing with each other and it really is like a mini united nations over there! Min is super friendly and a very sociable guy. Ask for help, and he'll give it too you. Very flexible rules, as long as you know the few important ones, the rest are pretty much up to you. I thoroughly enjoyed myself there! Thanks min!
