Source? Because that's definitely not unheard of let alone common. In fact, as a European I've literally not heard something like that.

Only time I had to bring my own bedlinen was in a youth hostel. For some hotels I've stayed in though, it would have been a good idea.

The only places I've heard of that do this are the most budget of holiday parks in the UK. The type of place where the TV is bolted down and you have to pay for your own electricity.

Where?

I’m not trying to brag but I’ve been to all seven continents of this world and many places in Europe. Never once have I seen this.

I also doubt this. If the hotel has at least one star, providing towels is mandatory for them: https://en.wikipedia.org/wiki/Hotel_rating#European_Hotelsta...

Presumably, bed sheets are so basic that they aren't even listed in the star criteria. Even in youth hostels, you may have to put the sheets on yourself or they might cost extra, but you don't need to bring your own.

Sorry that’s absolute nonsense

Did you have some weird experience that you’re extrapolating wildly?

It's definitely a thing in some European youth hostels. Never seen this in proper hotels though.

I live in Europe and have been to my fair share of hotels (though mainly in northern europe), and have never had to bring my own linnens. Never heard of it either.

Its different for hostels tho

Nope, that’s not a thing
