My flight was delayed about 5 hours and I arrived through the night/ early morning. However, Olga assured me she would wake up to let me in and it wasn't a problem. She was also super kind and pleasant. The location was SO good for this change in schedule and for touring around Barcelona. The only downside was that the people in the building were a bit loud and the elevator made a lot of noise which kept waking me. I probably should have brought ear plugs but overall it was a great place to stay!
