The location is great! If you like taking a walk, like us and pick this place, you wouldn't need to use any transport. There are many supermarkets, cafes and restaurants near by and all major sights that you would want to see in Barcelona are reachable in 5 to 45 mins walk.
There were minor disadvantages in the place. It's small and cosy, the hosts could have done a slightly better job at cleaning it, but overall we are happy we stayed there.
