Dont really know about those islands. Only Terceria (or how ever you spell it). But if all the others looked like where I was at, you will fall in love with that place. I left there in 2012 and that place still reserves a spot, so peaceful and relaxing, the locals are great people. During the spring summer and beginning of fall there is usually a festival that last a week long and a different village hosts it every week. The bigger towns or villages will have the rave feel parties at night, while the smaller villages has that old village type felling to it (more authentic I should say)
