This place was in a perfect spot in Shinjuku as it was close to a train station, but still close enough to walk into the nightlife in Shinjuku. Nj responded to all my questions prior to my arrival and once I arrived, instructions were clear and didn't even have to contact him with any questions throughout my stay.
As a group of 3, we slept comfortably and used this place just for that. If you're looking for a place to lounge in, this may be too small as there's not really a kitchen table or living room per se. The bathroom is also small. However, it suited all of our needs and had a washer and a rack to hang dry our clothes on the balcony. 7 Eleven was just down the street as well! This place is super convenient and would recommend to anyone.
