Good location: We came from shin-Osaka to Tokyo by shinkansen, from Tokyo station ginza line directions are one of better indicated lines. Not a lot of changes to make which is very convenient. Another point in relation to location, we went to Narita airport on our leave by trains, TOEI asakusa line within 1 minute of asakusa metro station. I would say for first time traveler in Japan and if not very familiar with subway/train system, the location is close (5-10minutes) to well connected station (Asakusa metro and asakusa toei). Definitely a good selling point. Very good especially if travelers on budget, saves a LOT of money compared to taking taxi. If you have good travel schedule you can save a lot of money that way.
Other than this, very well maintained private room as well as shared space. There's nothing to complain about.
