We will be in Spain this Fall for 21 days. On our previous trips, we've always brought a carry-on roller bag. I've been intrigued by Sarah Murdoch's (a guide for RS) challenge where she tried an ultra-light bag. I usually bring 4-5 outfits - 2 capri outfits, 2 dresses, and long pants so I purchased the bag (Amazon had a Lightning Deal!), and everything fits.

For those who have traveled in Spain, is it a location where roller bags have been an annoyance, i.e. lots of bumpy cobblestones between the train/bus stations and the city center, and I would really notice the benefit? Or, should I just use my normal bag?
Locations we're staying: Toledo, Madrid, Cordoba, Seville, Ronda, Granada, Frigiliana, Malaga.
