Hej Helene,
välkommen som ny Airbnb värd!
In Sweden, it is not that unusual to ask guests to bring their own sheets, or to pay extra for sheets. Especially if the listing is in a remote area and there is no cleaning service, so that the guests are also expected to clean and prepare the place for the next guest.
And it often works OK with Swedish guests. But international guests are typically very surprised when they arrive to find the beds unmade, and/or they are asked to pay extra if they want to borrow sheets and towels.
Many hosts have experienced disgruntled guests (guests tend not to read all info in the listing, and be surprised by things already mentioned…). Some guests cannot be bothered to make the beds, even if sheets are available. Meaning that hosts have to clean mattress toppers, pillows and down filled duvets between guests…
The majority (but not all) of Swedish Airbnb hosts therefore offer sheets and towels, included in the nightly rate.
I see that your new listing is in Gotland, not in Huddinge where you live. Will you have someone local to clean between guests? If yes, I’d suggest including sheets in the rent. Or, if you anticipate a lot of Swedish guests, coming by car: Offer sheets at an extra cost, but remind guests in your booking messages!
Good luck!
