My partner and I chose this place for our Tokyo trip as, like the advertised title, it is a bang for your buck! The rooms are exactly as they are pictured: very clean and pretty spaces. You have access to everything you need: toiletries (shampoo, conditioner, shaving cream, body wash), towels, fridge, microwave, stovetop, laundry (washer and dryer are combined), AC (very important for hot summers in Japan!!), comfy double bed, etc. We paid for the Wifi hotspot, and to put it simply if you're on the edge of deciding whether it's worth it: it's worth it. You need this as you'll likely be using GoogleMaps to navigate everywhere. Also, we discovered a little too late that there were even some dishes and cutlery for use, too, as well as an electric kettle for tea. We always ate out, but it's nice that Shu provides those things for his guests.
Like some others guests have mentioned, you do share the house entrance with Shu, so you may hear or run into him when he leaves or comes home. However, Shu has everything he needs upstairs (except laundry machine) and seems very busy with work most of the time, so your privacy will certainly be respected. If you're not super interested in hanging out with your host on your trip and just want to do your own thing, this is the place for you! On the note of the host, if you ever need anything, you can message Shu on here and he'll usually respond promptly, clearly, and informatively.
What's even better than this place though is its location. Not that far of a walk from Shinjuku Station, and only a few minutes away from Shin-Okubo Station, which we often used as a starting point for our excursions. Made traveling around Tokyo much easier than expected! The place is within walking distance (equal to or less than 5 min.) from 711, a cigarette store, FamilyMart and many great restaurants and shops. Rather close to the Kabuchiko area as well, which is a fun place to explore and eat good food.
One last thing: my partner and I stupidly got confused by the time zone difference and accidentally booked 1 day less than we needed and had to ask Shu somewhat last minute for an extension. He was very helpful and responded promptly to help us resolve this issue!
TL;DR: Perfect place and location. Highly recommended. Kind and communicative host.
Thank you Shu for a great first AirBnB experience! :-)
