I recommend Joan's place. It is a nice little apartment that is just perfect for a single traveller or a couple. There is also a couch that can double as a bed for a third but really the place is too small for more that 2 people in my oppinion. The checkin was really smooth and effortless, and Joan was really attentive asking in advance about my and my girlfriends arrival times so that he can make sure someone will be there to hand us the keys. I liked the look of the apartment, and the location that is 5 minutes away from Sagrada Familia and from the subway station. You can get to the center of the city (Las Ramblas, Catalunya area) in about 20 minutes. The only shortcomings that I can mention are the lack of a plug next to the bed (there is one but the lighting fixture is plugged in so you're left with the choice of reading lights or charging your phone/laptop. Another small inconvenience was the presence of a few really small flies that might have gotten in from outside before my arrival (I did not open the windows during my stay). The place was neat and clean so I don't think the source for the flies was from inside the apartment. All in all i am happy with my choice for accommodation and I recommend it.
