This place is amazing. Four of us stayed five nights here and it couldn't have been more perfect. Check in was super easy, as Finn had his (lovely) associate Luz meet us at the apartment to go over things and give us the keys.
There's a wonderful little balcony to hang out in the sun during your inevitable siesta from wandering around the city. The apartment was literally four minutes walk to the Sagrada Familia, and you can even see the towers from the balcony! Very walkable distance to most places, and also super close to transit links.
Highly recommend staying here, it couldn't have been more cozy. Oh, and because I hardly ever see this mentioned on Airbnb listings - the beds were super comfortable! Slept well every night.
