The nightgowns that were there to wear were super pleasant and everything was very clean.
Convenience store essentially onsite - there's a door directly between the two - plus vending machines with limited contents.
Some noise from trains and traffic gets in but tends to be quiet from around midnight to 6am which is the most important bit anyway, wasn't woken up at 3am or anything like that.
The bathroom was very compact with the toilet, bath and shower in one small room and we needed to climb into the deep tub to take a shower, which was a little tricky for me as I was still recovering from knee surgery.
