Really enjoyed our stay as a family of 4. It was very hot during our stay so we missed not having any air conditioning as the bedrooms get very hot, even with the shutters closed.
The villa is very well equipped and has all you need, with towels provided for shower and pool.
The pool is fantastic and we'll maintained by the gardener/pool guy who comes most days and is very friendly. It is a really good size, with a gradient which offers a shallow end for children. The pool is definitely the highlight of the villa.
Whilst Valldemossa is within walking distance (approx 10 mins) you do have to walk down a busy road for the first 20 metres or so, which I wouldn't really want to do after dark. From there you can follow a dirt track to the village.
About Valldemossa itself, it is a beautiful village but restaurants generally close around 8 or 9 with one or two open later.
As with most of Mallorca, mosquitoes and wasps can be a nuisance so take plenty of spray etc.
We had a very pleasant stay and Lourdes really looked after us and replied to every query we had.
