Marissa's flat is wonderfully central, with comfortable beds and charmingly-bizarre furnishings, and tall bright windows with Juliet balconies. It feels like an old family home, that's been rapidly evacuated just before you arrived. The location is perfect - near enough to both the old town and beach for a short walk, but in a normally quiet area.
Marissa herself is extremely accommodating about arrival times, and gives you a vocally-ebullient tour of the flat when you get there - her daughter (also called Marissa, unless I'm mistaken?) speaks English and can interpret for her mother, if you don't have Spanish.
We'd heartily recommend staying here - we want to come back as soon as possible!
