If you come by bus…
Granada has a bus station. Outside the station there are stops for intercity buses. As an alternative, you can also acquire taxi services. If you choose to get intercity bus lines you must take the SN2 line and then change at South Avda with LAC bus. LAC bus goes to Gran Vía Street. You should get off at the last stop on this street which is also the Cathedral stop.
You can cross to the other side of the street and walk to the end of it in the same direction that the bus was going. Reach a junction where you will have to cross to the other side of the street and you will be in the Reyes Católicos Street. Let your right the fountain of Queen Isabella and Christopher Columbus and up the street a few meters called Pavaneras. Take the second street on the right, San Matías Street. Walk about 2 minutes down the street and find the Gar-Anat Hotel on your right, just on the corner of a square. This square called Plaza de Peregrinos.
