Tommy and Wei were a dream to communicate with. They responded promptly and thoroughly to us. Their listing was also easy to find and very close to the station. It's in a very central location with quick 15-30 minute train rides away from most of the most commonly visited districts in Tokyo. It's literally right next to Kabukicho, so if you want to go clubbing or Izakaya hopping, you can easily walk back to your home base within 10-15 minutes.
One thing to note, however, is that Shin-okubo is VERY crowded and mostly foreign/tourists. We personally found that the touristy vibe was quite different from the pleasant Japanese culture we were used to from our previous visit to the country.
That said, I would still recommend staying at Tommy and Wei's listing for anyone interested in exploring Tokyo for the convenience of the location alone. It's probably best for younger travellers between 20-40 without children.
