Lovely to have you back Littlebird - So many things to do in the Town.
Don't miss Sunday morning market, and be sure to get into the square early for a nice spot of breakfast and people-watching.
A climb of the 365 Calvari steps is a must, with great views over to the sea from the look-out alongside the chapel. (Say hello to the collection of cats that live up there too!).
There is a second square at the bottom of the steps which is great for drinking and eating in the day, but is quite quiet at night.

I love the vibe of the old town. Very Spanish and you will be spoilt for choices for places to eat. The main square has a lovely atmosphere and July is such a nice time to go, as it will be warm till late into the night.

One of my favourite restaurants is Trencadora. Wonderful little courtyard, and hidden in one of the lanes off the main square. It gets busy, so is worth booking;

PP is only a 10 minute taxi ride (I recall that you stayed almost halfway between the Port and the Town last time)so a trip to PP is really easy.
I'm sure that you will have a great time!
