Did a year between Tenerife, France, Cyprus, UK, mainland Spain.
I’m pretty lazy, but Airbnb for all of them. For me it was key to see good photos so I could view if there really was facilities to enable me to work. I need a good sized monitor for my job (spreadsheets, presentations etc).
You do end up paying more, but you get to check out the reviews and as mentioned they tend to be clearly photographed.Bills are all provided and a good portion of the adverts tend to include the wifi speed.
I’m probably going to similar towards the end of Autumn and early Winter.
Edited to add:- On AirBnB they do tend to give decent discounts for long term rentals. It still isn’t cheap as going private, but you know you can just turn up and everything will be ready and the bills are paid monthly.
