We've stayed for 2 days in this NH hotel in the week before Eastern. In one word: AVOID this! All shops are closed, and the old center of the town is overcrowded with people wanting to attend or see the processions that take place practically from noon till midnight (and later) every day. We never thought there was still such a catholic devotion in this modern Europ of 21st century!
The hotel has a parking in its basement, but - judging on smashed windows from some care parked there - it doesn't seem 100% safe or sufficiently secured. The restaurant (called NHube) shows the name of Ferran Adria (El Bulli) in its logo, but we suppose this is only a (heavily payed for) marketing gimmick: don't expect any molecular magic on your plate. Apart from that, the quality is more than acceptable: we had lunch/dinner 3 times over there.
Again WiFi is free - as in every NH hotel - but only in the lobby, and... only for 15 minutes! In all other NH hotels we've been to, this was 30 minutes (still too short, but you can always renew your access codes at the reception desk).
There is a swimming pool on top of the first floor, but it had a "Closed" board next to it, and looked like not having been cleaned for a while to us, although the weather conditions at the end of April in Andalucia invited for a refreshing swim.
And last but not least: be prepared for a 2 to 3 km walk to the center of the town. A walk through a not very attracting suburb with some (closed) shopping malls and offices. Perhaps you should envisage a hotel closer to the centre.
