This past August we stayed both pre- and post-cruise at the H10 Catalunya Plaza...and we've booked it again for pre- and post-cruise this coming April...Very nice little hotel right on the Placa Catalunya...you simply cannot beat the location! Breakfast (included when booking on their website) was OUTSTANDING.   https://www.h10hotels.com/en/barcelona-hotels/h10-catalunya-plaza?tc_alt=87113&n_okw=h10 catalunya plaza_b__c_104201078872&gclid=CjwKCAiA76-dBhByEiwAA0_s9WygKt9YVbx_uyE
