Crag is in the David Munilla guides to 'Andalucia' and 'Cadiz'. May be available through Cordee? The Cadiz guide is certainly available in the Decathlon in Algeciras. The topos are crap in both guides - although the 'Cadiz' guide is quite recent some of the diagrams bear little relation to reality. But its 'work outable'.
I flew to Malaga. I would suggest that an hour drive is optimistic (unless you really hammer down the 'payage' sections of motorway but you can certainly do it in 2/3 hours meandering along the coast road - plenty of Lidls to stock up at!
The road from Tarifa to San Bartolo is lined with kite-surf centres all doing 'bungalow-style' accommodation. I think that there is a refuge in the small village below the crag as well. There is a pretty funky bar at the road junction beyond the crags where, if you have the bottle, you can watch Chelsea knocking Valencia out of the Champions league live - or equivalent! Tarifa is a cool chilling venue with limitless bars and hippy shops.
Mid December the temp was steady in the 20's and there was no rain for a week - probably pot luck. The environment is quite green so I would suspect there is some moisture comes in off the Atlantic!
At your grade range you'd certainly find enough to keep you occupied at San Bartolo for 3/4 days. There's loads easier and there are also quite a few trad multi pitch routes
Other crags?
Close by is El Bujeo; close to a military zone (there are many signs in the area warning of military areas - seems you can ignore most of them!) and a bit minor but a couple of days worth at your grade range.
Next crag is Castellar (N of Algeciras); worth a visit for the Castle! Probably not worth a visit just for the climbing - a few small slabby sectors.
A couple of hours away is Grazalema (might be worth moving base). Not been myself but it looks to be the major crag of the area - limestone rather than hard sandstone - loads to go at.
I really liked the area - if you'd like to have a look at scans of a few of the topos to give you an idea just PM me.
