I had an amazing stay at this apartment - it is exactly as described in the Airbnb listing.
To begin, Rachid is very communicative and quick to respond - sending us very helpful information and making sure we had everything organized for our week-long stay. His friend Xavi was there to let us in when we arrived and helped us carry our (heavy) bags upstairs.
The apartment was big, clean, and full of light, with high ceilings and two balconies. The kitchen was well-equipped for cooking, which was great for nights we didn't need to go out. We did a few loads of laundry as well. The shower was hot and had great pressure. The neighborhood was wonderful as well, we walked to nearby Montjuic for sunsets over the city and there were plenty of delicious restaurants within minutes of the apartment.
I could not have asked more - this place was perfect!
