Barcelona Hotel recommendation

[Buster]

We are off to Barcelona after Easter for 4 days without the children. We would love to find a really romantic place to stay. Robbie checked out recommendations back in November. anyone got anything to add?

Buster,
Take a look at lastminute.com - I've just booked what looks like a really nice 4* hotel (Hotel Colon - v romantic!) at a v reasonable rate - £75 per night. But there's loads of bargains on there so check it out.
