This is quite possibly one of the best deals in Tokyo - value for money
1. Great location: cute neighborhood which isnt noisy and still has plenty of restaurants, bars (check out ten ten ten for some good wine/sake) and 24hr convenience stores.
2. Max 10min walk to the nearest station... About 20 min to main Shinjuku station. Plus you are walking distance to some great spots like Tokyo tower (lost in translation bar), shinjuku park and several other places.
3. The house is quite comfortable: 2 bedroom + living space and a massive balcony to lounge with wifi and tv. Each room has 2 queen size beds, so you could theoretically fit 4 people in each room if you don't mind the privacy.
4. Rumika the host is an absolute gem that was there when we checked in and out. She was super helpful and extremely accommodating. Plus she knows the neighborhood and can guide you to the best ramen shops and bars.
We're definitely staying here the next time we're back.
