This isn't a high class hotel or fancy place, so do lower expectations a little. The sheets and towels could have been a little cleaner, so those who are crazy concerned about those may want to bring their own :) Otherwise, experience was rather great.
If you're prone to coming back late at night, there are two restaurants right below the apartment that open til 2am, a monjya-yaki restaurant and a yakiniku restaurant. There are also a couple of family marts and lawsons near the Hakusan train station which seem to be 24 hours, and a 24 hour side dish and bentou shop next to the Hakusan station. The last train back is slightly past midnight.
Extremely nearby Hakusan station, just a couple minutes walk, and it has a very homely quiet feel at night, as it is mostly a neighbourhood/ suburbs area. Walls are a little thin, so you do have to be careful not to make too much noise and end up disturbing your neighbours, but that is somewhat standard for Japanese apartments.
The host is pleasant and accommodating, and someone will come in to clear the dustbins and sweep the common areas everyday.
