Both north and south Costa Blanca would be suitable locations. And regarding price of property well that depends on many factors. It isn't actually true to over generalise and say the north is more expensive, larger older villas with good size plots are often more common in the north and very keenly priced. (Even further north and inland from Valencia you will find property is less expensive but cooler still in winter). So your budget and what type of surrounding you are seeking will determine what you can buy no matter where you look. The main difference is topography and weather - if you like mountains and valley views go to north Costa Blanca, if you want flatter countryside and drier slightly warmer winters in an agricultural area then go to south Costa Blanca.
If you are looking for peace and quiet then country properties are reasonably priced, but both you and your guests will be car reliant. If you opt for town or resort living then larger plots are pricey and wont be that quiet. You accessibility from an airport with all year round flights (such as Alicante) will also need to be considered - people don't want to have to do a long drive after their hours of travelling. If you are offering airport transfers then you also have to cost up fuel, time getting there and back and maybe motorway tolls. I'm sure these are factors you have already considered.
Take your time to research your market. The Spanish are not necessarily going to go to yoga retreats or classes run by the English. Your target market is more likely to be northern Europeans either living in Spain or coming on holiday specifically to your retreat. Check out your future local 'competition' and be able to finance your first year in Spain to give yourself time to get established.
I wish you well in your new venture.
