Playa Andaluza is only configured with 2 bedroom and studio units (at least that's what they told me when I checked in this December).
The Wyndham nearby usually has a ton of inventory (there are like 6 different property names on II) , but it looks like there is nothing in II your week, just the week before and after.
Wyndham Grand Costa del Sol offers self-catering suites with the facilities of a top hotel. Family-friendly resort with restaurants, bars, kids club.

Here is one of their "Luxury" units for your dates. I was considering booking one of these, but I went down a rabbithole trying to pair up the resort codes on II with the bookable inventory on their website:

But more realistically if you need a 1-BR, this is $140-ish per night:

Good Luck! I'm looking to go back this winter.
