@Phyllis95 Nice to read how much you do to be a responsible human on this ailing planet. Maybe you should make sure to word your listing so it's right out there that guests who are environmentally aware and dedicated to recycling, not using plastics, etc. are welcome and will be a good fit with your listing. I'd also re-iterate that in messages to the guests when they book or request to book.
As far as towels go, I hate to admit this, as I avoid patronizing them as much as possible, but I bought all my guest towels at Walmart. I got nice thick ones (although many hosts prefer thinner towels, as they dry faster and don't take up as much space in the washer) and they have actually lasted for years and amazingly, no guest has ever stained them (I don't get the heavy-make-up, fake tan type guests, and I only host 1 guest at a time, so there's no issue with the tell-tale signs of sex). I know I didn't pay more than about $8 each for the bath towels. One guest even commented on how nice they were and asked how I keep them so soft, but I have no idea- I don't use fabric softener, and I don't even have a dryer- everything gets line dried, which you'd think might make them stiff, but it doesn't.
