The host had someone welcome us at 20:30 on a Friday evening, give us the keys, the WiFi password, and basically let us enjoy our stay the remainder of the time. There were no issues that required interaction with the host or building staff. Upon arrival we were informed that the room we had booked was double-booked, and therefore we were put into another room that provided identical facilities to the one described. This seems to be true, so no qualms there.

The apartment is spacious, there are 3 bedrooms, a living room, a dining room, a kitchen, and 1.5 bathrooms (not 2 bathrooms, as advertised). The only discrepancy with the description was the unusual fact that the apartment had two separate showers, but only a single toilet. Usually, 1.5 bathrooms means that there is one shower, and two toilets, but this was the opposite case. It was not a problem for us.

The view is tremendous, as advertised, and the location is stellar: 5 minutes walk to Sagrada Familia metro. All in all, quite satisfactory.
