Lina's house is great.
The house is about a 5 minute walk to Honancho station, from which you can reach the entirety of Tokyo, and in about 40 minutes you can walk to Shinjuku (should you find yourself there after the trains stop running).
Additionally, suginami-ku is a really nice part of Tokyo, so there's a ton to do within walkable distance once you're done seeing the major sights in Tokyo.
The AC in the guest room is fantastic, and she has an unusually nice coffee maker, which she was happy to let me use!
I hope to book Lina again the next time I go to Tokyo.
