Kei and Kotaro are really nice hosts. Lucky for us, we catch them during their holiday, so they brought us to Yokohama, doreamon museum, fully made use of our JR pass last day. Their apartment is about 15 mins slow walk from the station, but from the station, it's easy to get to harajuku, shibuya, shinjuku, Tokyo station and more. We had a great time with Kei and Kotaro! Hope to see you soon again!:D
