I would suggest to add extra curtains around the bed, as every time someone moved about or turned on the light, it was fully visible and disturbed my sleep (usually I have a sleep mask, but lost it a few days prior to my stay so it was very noticeable that a section of the curtain was missing.
It would also be helpful, if there was a ramp for the staircase, and made some adjustments for the elevator. I was travelling with two large suitcases, and I could barely manage to get upstairs.
