FROM THE AIRPORT BY TAXI
The price of a taxi to San Miguel Bajo in the Albayzin should be 30-32€.
As in all walks of life there are a minority of bad people who will overcharge you.
There seems to be little effort to discipline the bad taxi drivers who give the majority of good ones a bad name.
For this reason I advise you to look at this page about avoiding getting ripped off by taxi drivers.http://granadainfo.com/taxis.htm
This journey should take about 35 minutes. AIRPORT BUS THEN C1 or C3 MINIBUS
If you take this option the price of the bus is 3 euros per person.
A trip on the 31 bus is 1.20 euros. So this option will cost 12.60 euros.
It could be a little taxing getting 3 suitcases onto the bus and off again.
If you are worried about this then get off the airport bus at Jardines de Triunfo
where there is a taxi rank and get into a taxi. There is a taxi rank next to the big pole with a Spanish flag on top.
You can see the aiport bus stops on this page.http://www.granadamap.com/airport/bus_stops.htm
If you get off the plane and go straight to the bus there should be no problem with missing it.
When you go out of the arrival area where you pick up the suitcases just turn right and go out of the door at the end.
You should see the bus waiting.
This journey should take about 50 minutes. Other usful links
