I had a wonderful stay at Paula's apartment! It is SO close to the centre of Seville, you can walk to all the sights within 20 minutes, and there's amazing restaurants, bars and tourist attractions right on the doorstep. The apartment itself is cosy but sufficient - big roof terrace for sun bathing and outdoor dining! The sofa bed is huge and very comfy too.
Slight confusion when we checked in - I was coming with my dad and yet we didn't have sofa bedding provided, so just make sure you ask for this in advance.
Otherwise, a perfect trip, very very happy!
