Had a really nice stay Elías' place. It's really luminous, with a great terrace and double height, and feels spacious and airy as a result. Yes, there are lots of stairs (I counted almost 100) – but that was expected, and I didn't mind a bit of enforced exercise after all the bread and cheese you tend to eat in Spain. We spent most of our time outdoors, so while some spaces are tight and the amenities pretty basic, this didn't detract from our experience. As others have noted, the location is great – a quick 10 minute walk from Sants station, where you can hop on the metro or trake a train to Sitges or Tarragona, and overall seemed like a good value. Elías was super responsive and hospitable, and made our stay that much more pleasant!
