I think most people on vacation would rather not cook, and therefore don't value kitchens. There are some long-stay brands that cater to people who want kitchens but that doesn't seem to be the mid/high-end leisure travel market.
Toilet brush, I mean, they have people who will clean the toilet daily. Not a perfect substitute I agree, but also not something I've ever really thought about.
[edited to add] > Isn't the reason Airbnb bookings are down because interest rates are sky-high worldwide to combat inflation? Travel, in general, should be down if the reserved banks worldwide are doing their job.
Other way around. Prices are high because a lot of people are traveling, which is being folded into inflation numbers. Prices are high because demand is high relative to supply, for lots of things, but especially for travel where the market is still riding the post-pandemic rebound.
You are right that reserve banks are hoping to reduce demand for things like travel, but that will yield lower prices. Consensus is that rates at current levels are not doing that yet, and I think in past recessions, layoffs led demand drops.
Note also that Airbnb bookings are down but hotel occupancy is right below its 2019 peak. [1]
