Recently some unique concept hotels have been built. I picked "First Cabin" long time ago, but I didn't know that airplain concept hotel has 17 locations already. The one I want to visit is"Book and Bed Tokyo". "an accommodation bookshop" is their theme, you can stay and read all books freely. Even you don't read them, I think it will be comfortable be surrounded by books and enjoy silent mood. More hotels will be build until Tokyo Olympic, however people doesn't want new hotels for only one time events. So finally Airbnb has started to gain attention.
Here are some very very charming place you can find in Airbnb in Tokyo.
Tokyo Guest House. I think foreign people like this traditional mood.
Mitaka Tenmei Hanten Jutaku 303 This is a famous designer's apartment in Mitaka city.
Historical Nakagin Capsule Tower : This building is designed by Kisho Kurokawa in 1972. The one of important work of Japanese Metabolism movement. It is very nice that retro near future mood, but unfortunately they don't have hot water.
Modern Art Garally : Your dreams must be colorful when you sleep in this room.
Ginza Omura : You can enoy cookig in this big and nice kitchen.
