Just got back from a week's climbing in Costa Blanca in a group of 4. Our usual accommodation (in La Nucia) not having been available, we went for one of the houses in Abdet (run by Tom Phillips).
We were very comfortable; there was loads of space, and it was very reasonably priced.
Also, it was great to be away from the coast for a change, and feel more up in the mountains. The situation is great, with views down the valley to Guadalest and beyond, and there's climbing on the doorstep. We initially worried that we'd be adding to our travel times, but actually, many crags can be reached "round the back" via the Alcoi road; Montesa seemed justifiable for the first time; we also got to Forada surprisingly quickly (and both crags were great, by the way).
