Keiko’s place is located on a mostly quiet street about 5 minutes from Shimokitazawa. It’s small and clean, the air conditioning is powerful, and the WiFi is fast. Because one of the windows faces the street, large trucks can be a bit noisy, but I slept soundly every night.
5 minutes down the street is a coin laundry, which was fast!
Strongly recommend Coffea Exlibris. An excellent coffee shop.
