We had an absolutely wonderful time at Shin's place! It's super cozy, and we loved how it was a little away from the hustle and bustle of downtown Shinjuku. It's very close to the train station, so taking the train to get anywhere is easy. We had everything we needed, and the apartment was nice and clean. The pocket wifi strength was a little weak at times, but overall not a big issue.
Would definitely recommend this place, and would love to stay again - like a home away from home!
Thank you for your hospitality Shin! :)
