I got to enjoy almost a full week at Antonio's airbnb. I didn't get to meet Antonio in person, but he was very responsive with my messages and letting me know how to check-in and check-out.
The airbnb itself has a personal touch to it. The decorations and style of the airbnb were enjoyable and I took advantage of the A/C during my stay. It's about 5 minutes to a couple of metro stops and there's several of shops nearby in case you need to pick up anything.
And it's very close to La Sagrada Familia. I walked by it everyday and enjoyed seeing it all times of the day. Very beautiful to see on my walk back to the airbnb.
