Our stay at Maria's place was great. Her house was in a great location - very close to Sagrada Familia and the metro, and right outside her apartment is a taxi stand. Getting around was easy. There are a lot a restaurants near by. And having a second bathroom was super helpful for our family of four! I guess the only complaint would be that it got kind of loud at night with scooters and cars driving by. Maria is a great host - gave us great guidance on what to see and how to get around in Barcelona and she has a bunch of brochures with things to do. I recommend!
