Interesting question. I never paid attention to this as I bring my own towel. I know at Torch Beachclub they will provide you with a towel which is awsome, all black with a white Torch Logo Sign. I asked if I can buy one. It was €5 which I am sure went to the waiters pocket, I do not care, but I use it all the time. Best Beach towel ever,lol
It does not really matter, on the promenade you can get beach towels for as low as €3, no need to rent. When your vacation is over and you do not want to take it home, just leave it and someone else will probably pick it up
Thank you so much, Alex. That's a big help!
