Jessica and her daughter Diana are extremely friendly, and actually live at the location, providing a unique look into the local culture. Her house is in an extremely convenient location: 5 minutes away from the train station, which runs directly from the airport (Make sure you buy a T-casual ticket!), 10 minutes from Sagrada Familia, and 30 minutes from the beach. The room is small but cozy, more than sufficient for anyone going to Barcelona, as you will be spending most of the day outside.
This lady really opens up her house to you, allowing you to use her washer/dryer, her entire kitchen, and her fridge. She provided two towels, two hand towels, a beach towel, sunscreen, and even offered an umbrella when it rained. A couple things I do need to point out: this building has no elevator, and you will have to carry your own baggage up two flights of stairs. There is also no air conditioner, but a fan will be provided.
I had a blast in Barcelona and will make it a point to come say hi the next time!
