This house is centrally located just 2 subway stops from Shinjuku. The sasatsuka train station is just 10-15 minutes walk away and there are a lot of restaurants and late night dining options. The house is really well maintained and spacious in Tokyo standard. The bathtub is easy to use. Check in and check out were easy and instructions are super clear. Hiro is really responsive too.
First floor is the garage and storage space for shoes and maybe luggage. Second floor has the LDK (living dining kitchen) and bathroom with a tub and shower. Third floor has 2 spacious bedrooms. My background is I’m a builder in USA and have 3 young kids so I have really really high safety standards. The only thing I’d pay attention to is the stairs does not have hand rails, and are made of slippery materials, stair edge is also durable aluminum which could be edgy if you fall. Please make sure you don’t wear socks, especially if you have young children or elders.
