It's very easy to access and recommended when you bring luggage, because the station is offer an elevator so it will be easier for you bring your luggage from or to airport... But you need to transit first at nippori station or at tokyo station... From mikawashima station you will clearly see the hostel, so you wont feel any hardship for finding it... For you who are walking too much all over tokyo, this hostel have a foot messenger machine and a public bath, so you can relax after a long tiring ans fun day trip at tokyo... they also has 1 shower room on 1st floor so you also can have shower there if you're not comfortable with thw public bath... They capsule is so comfortable, I have a really nice sleep over there and I will gladly stay there again for my next trip to tokyo... They sometimes have an unexpected event, like a bbq for watch sumida fireworks at summer... and kat-tun come to this hostel for interviewing and have fun with the foreigners so it will become a really perfect stay and experience for you.. Staff also very nice, friendly and helpfull... very recommended for you
