@Juan63 It has a great deal to do with the location. I'm in a touristy beach town where people come for a tropical vacation and on top of that, I'm in the countryside, a 20 minute walk from town and the beach. All that is made clear in my listing and I also market towards the type of guest who'll be a good fit, so the guests who are attracted to my listing are those who are okay with all that. Most just want to spend the day at the beach, eat out at one of the hundreds of restaurants here, peruse the shops, and relax and read a book, do some yoga, art, etc. They didn't come here to sit around watching Netflix, or spend their time online. As long as they can check their email, let their family know they arrived safely, maybe surf the net a bit, that's all they really require, and almost every restaurant and cafe in town has Wifi that customers can hook up to, so if they need more internet, it's not that big an issue. It isn't that I wouldn't like to have better internet, it's that it's just not available where I live.
For sure there are lots of people who need to work online daily these days, even when they're on holiday, or even have a lifestyle where they don't have a permanent home, but can just travel and work online, so no, my place wouldn't be suitable for them, but I don't see this as "losing" bookings. It's simply not suitable for those who need constant, high-speed internet, just like some places aren't suitable for 12 guests, or aren't in a central location where guests can easily walk to everything.
And BTW, I've had plenty of guests of younger generations and I can assure you they aren't all dependent on high speed unlimited Wifi.
