Actually the tourist office, (even if in this moment march 2004, is closed on renovations) It used to be a caravasar (like a hotel where the merchants lodged and where they stored their merchandise) of the XIV century
Here is the main tourist office, they will inform you about a new ticket to visit all the monuments
C/ Mariana Pineda, s/n, s/n Edificio Corral del Carbón
Telephone 958 22 59 90
Fax 958 22 39 27
Favorite thing: The tourist office, I recommend a trip here, get a city map and check availability of the Alhambra tickets. Located in a theatre (very near the cathedral) where apparently shows are put on some nights.
