My bf and I really enjoyed Hotel Amadeus in Sevilla - http://www.hotelamadeussevilla.com/
There were great comments on it on fodor's europe forum (type hotel amadeus in search box). We chose it based on their comments. It is quite charming - beautifully decorated and clean. It is in a great location - short walk to the Cathedral.

Right around the corner is a fun young bar. We were there over Christmas - the bar was closed Christmas Eve, but was opening at 12am Christmas Day. We had a fun late night there!!
