I highly recommend Jordi and Jonathan's place. They have worked really hard to make it a welcoming place for guests from all over the world. I felt like I was checking into a professional bed and breakfast. They want to do everything possible to make sure that you are enjoying your stay.
I really, really liked the neighborhood. So much that I would live there if I had the opportunity. It is a nice chance to get away from the tourist district and to see what a normal Barcelona neighborhood is like. I just found it really beautiful and the people in the neighborhood stores very pleasant and friendly. The most amazing thing is that the apartment is also super close to the metro, so you can get to the center of the city in no time. It's like the best of both worlds. I didn't do a ton of research before making the booking and I feel like I lucked out with this apartment. They have a good internet and desk setup if you need to work. The shower is also a 10/10.
I'm pretty shy around strangers and I've never stayed in a shared airbnb before, but Jordi and Jonathan went out of their way to make me feel welcome. You are not going to find a better place for your money!!!
