Illacat's place was great. The views in the photos are accurate... When you step out onto the balcony, La Sagrada Familia is right there. The overall location was great. It's not particularly close to the main tourist neighborhood, the Gothic Quarter, but there were great restaurants nearby (including ones with outdoor seating just a few doors down, with La Sagrada Familia as the backdrop) and a subway stop right on the corner. We didn't find it to be too loud, though we could sometimes here people going up/down the stairs. Everything was clean, and the host seemed easily reachable (we communicated through WhatsApp for the check-in). Would recommend!
