The apartment is really well equipped and in a good area not too far to walk to all the good sights and restaurants. We only stayed one night but were really happy with the great private shower and the very, very big, clean and enormously comfortable bed.
Be prepared that the front facing room can get a bit noisy during the day, as it faces the street (there are 2 more rooms which face the courtyard) but since the bed was so comfy we really slept well and the noise was nothing that some earplugs couldn't fix! We can really recommend to stay here when on a city trip to Sevilla.
