Have a look at Rui Olivia in the canaries ( futurventura)
it’s a old style hotel ( think Butlins in the 80s 😂 ) but very clean and
the location is amazing right on the beach and I mean you walk out of the hotel and your on the beach no promenade the hotel is actually built on the beach 😂
3 star decent food ( I’m picky and found plenty to eat )
friend is a veggie and had no complaints
lots of returning clients because it’s cheap & cheerful
when I stayed there 70 percent were returning guests
the staff are lovely and they have a great entertainment team for kids from my memory
30 mins transfer from the airport with Tui
it’s not luxury but you won’t get luxury with your budget but it’s basic & clean and if your with your kids they will have a great time
I went for two weeks AI and paid 2k in July last year
1week last week of July is 1650 from London airports
so a bit more than your budget but well worth it .
you can get the bus to the main resort for 1.80 euros one way and there is a supermarket 5 mins walk away and a shop at the hotel
you have choice of the annex ( huge rooms like mini apartments )
or the main hotel but either are fine
Free wifi in pool / reception area but not in the rooms
and in July / August it will be scorching hot
