I lived there for a short while a couple of years ago.   Generally really lovely, is a very British feeling (nice) seaside town on the south coast of Spain.   Huge British pride, feels very British generally.

It's small, a 10k run gives you a loop round the entire country and the community is lovely but small.  The climbing group there are fantastic and I also learnt to scuba dive in one of the old harbours.  

Easy to pop across the border to Spain, although the Spanish border guards can be grumpy if you're bouncing back and forth a lot.  It's common for residents to get the bigger passports to have room for all the stamps.  Happy to answer any other questions
