The space was much bigger than we expected.
It is well-located near a location metro station, and near the botanical gardens. Its also a short walk from Shinjuku station, which is a major junction to get around.
There is a hot plate, so you can also cook in the unit if you like. There is high-speed internet on wifi.
I would also like to compliment the owner who was very quick to respond to emails, and provided excellent directions from the local station to get to the unit. In a place where you can barely read the road signs, this is greatly appreciated.
