Here in spain there are a lot of "apart-hotels" with kitchens equipped like a summer apartment.

This. IDK if this exists in other countries.

In Spain, at least in my experience, it doesn't make much sense to get an AirBnB.

Prices are higher most of the time, and hotels can and do have better location and service.

AirBnB was supposed to be a mean for people to rent spare rooms temporarily.

I was curious about these. Is there brand of aparthotels in Spain that has a good reputation or that you or someone else would recommend?

Hawaii is like that too. Most of the hotels have a full kitchen and washer and dryer. Or at least the places I've stayed.

I wonder how hotels could do this effectively and safely.

Include a mini-kitchen with 2 burners and a small counter. Burners are disabled but could be enabled by request, or some keypad on the wall (child proofed). You can pick up a box of kitchen supplies (pots, knives, etc) from the front desk or request room service to cart them up.

Put the supplies back in the box before you leave (box is lined with a rubbermaid dish bin).

This would offset the cost of furnishing each room with supplies, while also killing one of airbnb's value props.

Extended Stay America locations have a "fully equipped kitchen" in every room so it's certainly possible and already happening.

The place I've stayed at in London a fair number of times calls itself a "serviced apartment" and includes a kitchenette. I don't really use it much other than the refrigerator but it's there and I've stayed there with a friend who would cook eggs in the morning.

I'm pretty sure some of the suite-style chains in the US do as well.

In Oz, you can often and easily find rooms in an ordinary motel that has pots and pans, a little 2 element cooktop/oven combo & a sink. They're more expensive to rent of course, but they're very widely available.

We also have serviced apartments, designed for the longer stays, but are generally only to be found on the cities.

This exist in Spain, it's called apartahotel. It's basically an hotel made of apartments.

Lots of places have a mini kitchen suite.
