It was a pleasure to spend 6 nights (2 adults & 1 child) at Nanako's place - one of the nicest Airbnb's we've stayed at in Japan. The tasteful and thoughtfully appointed apartment is situated in an elegant modern building, just around the corner from a great little supermarket, with many other amenities (including nearby sento), rail links, restaurants and other places of interest nearby.
Shimbamba is a peaceful, historically significant part of Shinagawa, with easy links to the greater metropolis of Tokyo and beyond.
Nanako was always very kind and professional to deal with, the information she provided was excellent, and she went out of her way to enable us to check-in early.
Many thanks Nanako!
