Staying with Leo was definitely one of the highlights of my partner's and I's trip to Barcelona.
We messed up, and landed in Spain (a new country for us) at night with our luggage. I do not recommend! The neighboring location at night isn't necessarily the best, so I would recommend getting to the airbnb earlier in the morning to prevent unnecessary panic.
Fortunate for us, Leo suggested we meet at a local bar, and he would walk us to his apartment. That was very kind of him. Leo was very hospitable and made us feel like we were at home.
The location is a nice walk to the Gothic Quarter. The apartment is small and quaint, with 3 bedrooms, 2 of which are Airbnb'd. There is no A/C in the apartment, but there are nice fans that definitely help cool the room. My partner and I didnt really plan to stay in the room much, so if that is you, this option worked out nicely for us.
Leo and his partner Dany offered us many suggestions, and we even had a night of listening to some of his songs (he produces music) over a few beers, which was a great way to end the night. Meeting them was definitely one of our highlights of our Barcelona trip and I hope to look for them again when we find the time to come back.
