Self check in was easy, with clear instructions to gain entry - wasn't quite sure locked the door successfully once inside the apartment, as electronic lock. Great location, with Urgel & Universitat stations a short walk away. Clean, well laid out apartment, with comfortable beds. Reception were really knowledgeable, helpful and friendly - stored luggage when we checked out, so we could continue exploring Barcelona, luggage free. Would definitely recommend.
Was rather concerned when I realised I had a pending payment for Sweet Inn, for approx £330, having obviously already paid through Airbnb - believe this was the deposit held for key cards, as now appears to have been removed from pending, and doesn't seem to have come out of my account, which was a relief.
