Pros:
1) Location was amazing. Almost right across Nishi-Shinjuku tram station and very close to conbinis. A short walking distance to the heart of Shinjuku too.
2) Hosts were very responsive so it was awesome!
Cons:
1) There are hair on the duvet covers which were disgusting. Almost felt like the sheets were not changed after the previous guests left. It didn't feel and look clean and very worn out. Maybe time to get new sheets!
2) Although the owners mentioned the house is good for 10 but that would be like staying in a sardine can! The house is perfect for 7- more than that it is suffocating. There are 3 rooms- 1 room with a bunk bed, 1 room with 2 double beds put together- unless you are OK to sleep breathing the other person's breath, or you never turn at all when you are sleeping, then fine :) I traveled with 4 kids and 5 adults.
3) Towels are worn out. Bring your own!
4) Soft, thin worn out 1 per person pillows.
Overall, an OK place but won't book again.
