Selina was amazingly helpful and accommodating. The place is easy to find and the check in procedure is quite simple!
The place is quite close to Myogadani station on the Marunouchi line. There are several restaurants that are open late close to the station, otherwise most of the things close pretty early. The paper factory gets somewhat noisy early in the morning (around 8am) on weekdays, but it's not too bad.
If you're looking to experience nightlife in Tokyo, it might be better to stay closer to Yamanote Line in Shibuya or Shinjuku, because it might be hard to get back really late at night. Otherwise, this is an excellent sightseeing base.
I recommend that you take the bike out and check out the area, as well!
