thx for the info , I have check the Bancotel, and the individual hotel website, in fact Bancotel offer cheaper than the Rivoli Ramblas own rate (25 euros /night), but since we are only staying for 2 nights, and we dont want to check out and check in to different hotel ( one for 2 checks, and one for 3 checks) to use up all 5 checks in the check book.
May be we will go for the Hotel Continental as other members have experienced.
Any other suggestion?
