Easy to access, this building was located near transit, and was walking distance to 7-11, and popular Shinjuku sights. Other reviews mentioned hot water, but we didn't have an issue with it. It does seem like it runs on a tankless system, so you don't get immediate access to hot water. We didn't use any of the kitchen amenities, but the mini-split ductless system works fine. FYI - The accommodation's are located up a flight of stairs (don't believe there was an elevator).
Things I wish we would've known: Wi-Fi was ~5mbps/second (would recommend e-mail only), the images were slightly different than the original photos (no shag carpet under the table, and seats had less cushioning). Personally, the shower was on the smaller side than any of the other accommodations we stayed during our two week vacation, but it worked fine. The location is accurate, but we didn't find a lot of well reviewed food options nearby. Felt like we had to venture out for that, but they weren't too far to find
