Choco's apartment was really nice and clean, containing everything we need. We were a handful, having extra guests suddenly but Choco was nice and accomodated us well by providing extra mattresses and recommending places to visit. The second level of the room is super warm despite turning on the aircon (probably because it's summer too) and Choco advised us to turn on a fan facing upwards, which worked well and we finally got to sleep above. There's also TV in the room, and we were thankful that there's a boiler too (it's our first boiler after staying in three apartments).
The location of the apartment was also really good, led us to Shinjuku within minutes and even more convenient because we can take rapid trains. There's supermart, bakeries, a shopping street and convenience stores nearby so you can roam around the area as well.
We loved our stay here and will definitely book again if we're going to Japan!
