Bobby, as said, no kettles in the rooms.
As for markets. We didn't see or hear of much, but most of the area was closed, due to it being out of season.
We heard that at the bottom of Calella old town they had a market on saturday but it was just fruit and veg.
A couple that we met went on a coach trip to a market (somewhere beginning with T) on sunday. We didn't see them after that so not sure if it was good or bad.
Sorry I can't be of any further use to you but like I said 90% of Calella was shut, with not much to do.
