I was excited for the house until I got there and realized I couldn’t flush anything down the toilet. So I called the host to confirm and I asked “What if I have to have a bowel movement?” His response was “you can use the bathroom but once you wipe with toilet throw the tissue in a plastic bag and then take it outside; you have to remember our plumbing isn’t the same plumbing from where you are from!” The entire stay we had to accommodate and find places to relieve ourselves because we didn’t feel comfortable taking used toilet paper and put it in the bag then throw it out. That was beyond uncomfortable for us.
I believe that should be notated in the house rules and policies that way it gives the guest a option to want to deal with it or not.
