You'll love this apartment for the neighborhood it's located in! If you're looking for a local-feel and cultural experience, choose this place. We stayed 6 nights in the apartment and each morning you could walk outside and see the local shop owners opening up their cafes and botiques, it was amazing. You're within a 15 minute walk of La Sagrada Familia and Parc Guell. I highly recommend this apt just for the neighborhood. You can walk 3 blocks in any direction and be overwhelmed with the options for food and drink.
The shower is a little tiny so just beware if that's a concern to you. There are two beds but one is certainly larger than the other. The smaller bed is a dorm-room size Twin. Again, it's worth it in my opinion but just a heads up!
