I think that the bathtub situation needs a little more curation. First, I did not like that I had to pay for all the bath salts and other stuff. Secondly, there needs to be a stable place to put drinks, hang towels, robes, etc.. I feel like your rooms will get disgusting quickly from people walking around dripping water everywhere.
Moving on, you need to install security locks on the doors, its a bit weird to only have the tiny locks available.
Other than that I loved this place so much and would DIE to stay here every night of my life.
