No worries, you've made a good choice.
My family and I stayed there last July. There are two blocks of apartments, each of three storeys. We were in a two bedroom apartment on the top floor, with its own roof terrace, as well as balcony. Reasonably well furnished, clean, and well looked after. The staff are helpful, although they can be difficult to find at some times of the day. It is quite quiet, as there are no restaurant or bar, although reception does sell drink and crisps, nuts.
The only downside to the garedns around the two pools were the number of ants - sit still for too long and you will be infested!
At present it is a quiet location, possibly the only problem at night being the level of street illumination, and some noise from the 'entertainment' at the Pollensa Park and Golden Lion.
Walking time into the square is probably 15 minutes (although I walk fast!). However it is only 5-10 mins to the start of the centre and restaurants/shops at the river bridge.
If we were going back to PP this year we would have gone back to Las Velas, indeed another family we met there are doing just that.
Its just a pity that the new ring road and distributor roundabout will be constructed outside the front of it within the next year or so, as that will probably spoil the location.
Hope this helps
