I had similar but usually because they hadn’t correctly applied discounts for long term stays so suddenly you were getting huge percentage off. If that happened I chose somewhere else.
I also contacted some Airbnb and asked if they could offer a discount for long term stays … don’t ask don’t get. They save on the change over costs so sometimes this worked fine.

Yes it would seem AB&B don't always work out the discounts with the owners. Whenever it has happened the owners have offered a discounted price for the month , you then have to decide if it fits your price range. Main point though is rather than being disappointed better to check the one month price with the owner with a message.

Moving to the Canaries would solve two problems at once. Pleasant summers and warm winters is what you can expect in Las Palmas, and if you want a bit more heat then you just pick the southern side of the island.

Currently 24-25C during the day this week and >20C in the winters too, which is why we don't need aircon or heating.

Add to that a 75% gov't rebate (for Canarian residents) on all flight to/from the Canaries to anywhere in Spain and those weekend trips to Madrid or Barcelona become a lot more affordable.
