We are also looking for a 5 night in Barcelona. A colleague stayed at the AC Sants and said the location was excellent. Across from the subway and in town in no time. There is a mall with a carfour steps away as well if you want to pick up food at the grocery store. That said, no breakfast or platinum recognition beyond a possible room upgrade. Redemption rate of 17.5K nightly makes it attractive especially if you can make it 5 vs 4 nights for 70K. I am looking at booking this vs the Irla based on his recommendation. If you wind up there update the post please as would appreciate your spin assuming your arrival is before ours in August.
