I stay in the Raval whenever I go (have a look for Hostal Gat Xino or the cheapy Hostal Gat Raval) - near the MACBA art gallery yet and 10 minutes' walk from Plaza Catalunya/ Las Ramblas, yet feels a bit off the tourist track.
The weather's still pretty decent in December - shirtsleeves rather than shorts weather - went a few years ago for some gigs and still managed to spend the afternoons reading a book on the beach. Should be pretty easy to get tickets for the Nou Camp too (buy from the "Servicaixia" cash points inside banks) - just don't do as I did and get pickpocketed on the way back!
Went for a stag do there last weekend and went to the Villareal match. Stayed in a hotel called NH Master (reasonably priced, quite smart and walkable to the harbour and Ramblas).

It was 18C during the day when I went (around 10 December).
Can recommend Hotel Gran Via - just 100 yards or so from Placa De Catyluna
Or bit more cash Hotel Universal - 5 mins from Ramblas.
do beware of pickpockets though
