Self catering, on beach, indoor heated pool, Canary Islands

[TooIntrovert]

I'm trying to find a holiday that fills the above criteria

Need indoor heated pool for son (health reasons to do his physical therapy)
Self catering or a kitchennete we can cook in
On a beach as we want a beach holiday!

Canary islands ideally but this is the most flexible...something that's warmish (to a Brit) in April

I can't find anything that ticks all the boxes though, can anyone help

TUI Blue Flamingo beach in Lanzarote would tick those boxes. It does say the indoor pool is for over 16 but that young children can use it in the morning as long as they are with an adult. It’s right on the doorstep of Flamingo beach in Playa Blanca.

Thank you! We booked something very similar in Gran Canaria as they were booked up
