Sara's place was great, really lives up to the bohemian description - just take a look at the art and the literature on offer and you'll see what I mean. The apartment has everything you need and the location is really central so is great for staying out late on Spanish evenings. Obviously that central location means it can be lively at night but not so much you can't sleep through it, but if you're staying centrally you'll probably want to be out having fun with everyone else anyway. A great place to stay in the city!
