I was looking at the hotels website and price. I need to find out whether which hotels that offer free shuttle airport bus because I arrive in the Barcelona Airport at late night - at about 10pm. It will be my first time visit there and I have no idea what it looks like. I am worried that the public transports will be closed at late night. So do you know which barcelona's hotels that have own shuttle airport bus??

If not, what other options have you got??

Thanks
