Awesome apartment in what turned out to be my favorite neighborhood in Barcelona. Spent a majority of my trip eating and drinking my way through Gràcia. So many cool local bars, cafes, and restaurants just down the street. Obviously all of Barcelona is beautiful, but if you want to truly immerse yourself in the local culture Gràcia is where it's at! And you're still in super close proximity to all the must sees like Sagrada Familia, La Rambla, and the Gothic Quarter. We walked to all of those places, between 15 and 30 minutes depending on where you're going and how fast you're walking, but the Joanic metro station is only half a block away and the Barcelona subway system is really easy to navigate. The apartment itself was very safe, spacious, clean, and easy to get to. What you see in the photos is exactly what you get. Laia and Aleu were very accommodating and always responded to messages quickly.
As far as getting there from the airport...when we got in around noon on a Monday, Uber rates to the apartment were about 35€. Not too crazy, but we decided to save a little money and took the Aerobus which cost about 7€ per person. We got off at Plaça d'Espanya and then jumped in a taxi to the apartment which was 12€. On the way back to the airport after our trip we took the metro, which involved taking 3 different subway lines. That sounds more complicated than it really is, but was way easier to figure out once we'd gotten used to taking the metro after a few days in Barcelona. Definitely doable on your way in, but you might want to familiarize yourself with the subway map ahead of time to mentally prepare. Metro tickets to/from the airport are just under 5€.
Thanks again to Laia and Aleu for being such great hosts! I 100% recommend this spot.
