Esther was a great host. We did have a bit of problems with the keys and locks. Older locks do this but if you stay here I would recommend making sure you can lock and unlock both the downstairs and the upstairs locks without a problem. I stayed 5 nights and there really is a lot to see and great places to visit. However, if you are an introvert like me, just know this really is smack down in the middle of the city so lots of people all the time. However, Esther's place does feel like a little oasis away from a busy city. The metro access, about a 5 min walk, is great and gives you access to the beaches, La Sagrada Familia, Casa Batlo and pretty much anything else you want to see. You will get a workout from the stairs, pack light. I ended up staying my last night near Castelldefels, fell in love with this beach. It's an easy metro and train ride away. Enjoy!
