Great value and location! You're about 10 minutes to the heart of Shinjuku and very close to popular destinations such as Golden Gai, Robot Show, etc.
The space itself is great. The bathroom is amazing and you'll be able to take baths. The beds are clean and comfortable and sheets are provided. We were able to use the fridge on the second floor but honestly didn't spend much time there since we were mostly out. This was a airBnB especially since we looked at similar places at hotels which were significantly more.
