The area you mentioned is called Montemar...or it's proper name is Montemar Bajo because the area above the main coastal road is called Montemar Alto...... Bajo means low/below. Alto means high/upper/tall with the coastal road separating the area in the middle.
The street is called Calle Salvador Allende and the British/Irish bars will be open...or the ones still in business should be.
Hotel La Barracuda, I haven't stayed there , but I did notice last week that by the side of the front entrance and attached to the wall there was a huge sign giving notice about a programme of modernisation/refurbishment.
I don't know if that has taken place and the board hasn't been removed, or is currently taking place or will be happening shortly.
