This was one of our best Airbnb experiences. Alex is warm, helpful, and reliable. He maintains a beautiful home and keeps it clean and well stocked with basic necessities.
Just a heads up for light sleepers like me: the room is bright and some of the sounds of the street do come in but I did not find this to be an issue. The neighborhood is generally very quiet and the sunlight in the morning got us out the door feeling ready for the day.
We absolutely loved the Poble Sec and Santa Antoni neighborhoods as they were further from the high traffic tourist scene and therefore provided a more local experience. Alex's place is also right down the street from Montjuic. We had a wonderful time walking through its many gardens and museums. It was also close enough for a short run!
In essence, I highly recommend staying at Alex's place! I'll definitely be coming back here when I return to Barcelona on my next vacation.
