We would have liked to meet Keita in person. It would have been cool to connect a face with a picture. Meeting the host is, for me, a part of the charm of renting an Air BnB. But that is fine.
Keita and his partners are very thoughtful hosts. I enjoyed the packet they put together to help guests navigate around the immediate neighborhood and gave many great suggestions of places to go in greater Tokyo.
Keita's place was perfect in many ways. It is within a 7 to 10 minutes walk from Shinjuku Station (West Exit), and, because of so, there are plenty of eats, shopping, and entertainment all around. There is a Family Mart convenient store across the street, and, for those who want to save a few bucks or get tired of eating out, a grocery store is also nearby.
The apartment has many modern touches, and it has more than enough room for 7-8 guests. There is one double and two single beds on the lower level. Guests can find a spacious master bedroom with a king bed and a smaller bedroom with a queen bed on the upper level. For the three of us, we had more than enough room to spread out.
I do, however, have a bit of caution for those who choose the rooms on the upper floor. The master bedroom is spacious. But do be aware of the two samurai suits of armor (including the face masks) and samurai swords on display in this room. For those who may not be ready for this art or interior design concept, these displays could be a bit unsettling. The smaller room is rather comfortable but, because the fire escape door is in the same space, eye masks might be in order. The exit sign is bright.
Overall, however, Keita and partners are wonderful hosts, and the house is excellent in many ways. I highly recommend it.
