Stayed here for 4 days with my family, so a total of 4 people. Great place in a great location, very bright, with Sagrada Familia visible right outside the window. Air conditioning available in all rooms, with one room having a double bed, one room a single bed, and a sofa in the living room can be turned into a double bed as well, although the air conditioning in the living room is pointed right at it, but it can obviously turned off, as all the units have separate remote controls. In general, everything is as described.
Metro/bus station as well as supermarkets and bars are all about a 5 minute walk away. When it comes to the beach, it's about a 50 minute walk or a 25-35 minute public transport ride.
As opposed to the other reviews, we had no construction work noise during our stay, but there is definitely construction sites around the house, so it is entirely possible some people might experience some disturbance.
The host was easy to communicate with, replied fairly quickly, and helped us immediately with the few requests we had. A hair dryer that did not work upon our arrival was replaced immediately, as there is a company office a couple of floors down from the apartment.
There was also a tourist tax we had to pay via cash upon check-in, which was not included in the booking price, and at the time of our arrival in August 2022 amounted to 4 EUR per person per night. We were, however, informed there will be a tourist tax after the booking was complete, so this is more of a bit of information to have before the booking, so keep in mind extra costs can incur.
Overall a great place in terms of location, comfort, and value, would likely stay here again. :)
