Only had 2 days with them but seemed to be OK. Many stw posters also recommend them.
With the current exchange rate issues it may be a bit more expensive to eat & drink out down on the coast than some of the other operators up in the hills.
A plus point is you get more riding for your ££s due to the least amount of travelling/transfer time.
The riding is also more like home over rocky terain and through woodland than up in the Sierra Nevadas where it is a bit more open, sandy and exposed. Bit warmer inland tho.
Others to consider are Joyriders and SeasonalyUnadjusted.
Best thing to do is e-mail them for info stating your riding experience and what you want out of the holiday. Found them all very helpfull(but Spanish time = slow!!)
Search places like flickr, photobucket and other photo hosters for pics.
