Getting to and into the AirBnB was fairly straight-forward. The apartment had some really good character indicative of Spain such as tiles and roofing that made the place feel pretty authentic. We didn't have much problem with noise, but like everywhere in Spain, the walls are fairly thin.
Everything was as expected from pictures and info provided, and it was pretty close to various Gaudi buildings and sites.
I do have to note that the place was draftier than the other AirBnB we ended up staying for the remainder of our vacation in Spain.
Checkout was extremely painless with just having to place the keycards into the box at the table.
