Beautiful town on the coast with a wonderful drive through the mountains if coming from Malaga side. Very charming and picturesque. Quite hilly in places, but a nice flat busy square with plenty of cafes and restaurants and excellent views.
Some really nice hotels but do beware if you go one of of these unamed holidays- we were put in a hotel up a hill which would not do for elderly or disabled. Nearly fell off the hill when looking for a bar as our small Spanish hotel shut up shop very early! Lively in the town though- but it was a good 20minute walk.
Nice beaches, nice caves, nice shops and ideal place if you are not bothered about travelling any further than that.
However if you want to see a bit more of Spain ie Gibraltar, Marbella etc- you are a long way out!
