Takashi and Li were great! I just needed a room for a couple nights and their place was unique and very very clean. The room and futon were comfortable. It was also helpful that they were flexible with check-in/check-out times. Their home is about a 10 minute walk from the JR Osaki station and was easy to find. Li showed me a cool shopping street nearby and mentioned a sento, which I unfortunately didn't have time to check out.

If I needed a place to stay in the shinagawa area in the future, I'd definitely stay with them again. They are well-prepared for guests.
