Marilo Y Tono's place is brilliant - really stylish, arty and cool, we loved it! The location is really central, very easy on the metro (25 minutes or so) and perfect for walking around the city centre. The flat has everything you would need, sparkling clean and is a really nice space to hang out. Marilo Y Tono had some great recommendations for food and places to go, the tapas restaurant is particularly good.
