Her home was located a bit out of central Barcelona, but is only a 2 minute walk from the metro and walking distance to the beach. There are plenty of bars and restaurants nearby, and the community is always congregated in park squares.
She was very kind and helpful with our luggage situation (our luggage was lost for our entire stay) and she helped us figure out the metro system.
The house is clean and nice, but a note for those traveling in the summer: the air conditioning mentioned in the listing is only placed outside the room, in the hallway/living room area. But if you keep your door open you can get the breeze. The listing also does not mention their cute kitten, which was fun to play with but a bit of an issue for my partner, who suffers from mild allergies.
Overall, we had a good experience with Natalia :)
