I had a great stay in Sarah's apartment - everything is as described in the photos and in the text. Sarah was very quick, helpful and friendly in communicating. The studio is conveniently located - metro station just around the corner, 10 mins walk to Sants Station... and very well equipped.
I did find it a bit noisy sometimes at night, as there are small cafés just downstairs and there were a few "parties" going on in the neighborhood, so if you're a light sleeper (like myself) you might want to bring earplugs. All in all, totally recommended.
