We enjoyed staying at Enrique. The location of the flat is great - right in front of Sagrada, metro is in 1 min, supermarket is in 2 min. It wasn't noisy, it has air conditioning (which you can use as a heater a bit when the winter is), it's well equipped and has everything you need. It was 4 of us and all of us had comfort sleeping there. The only thing is bad wi-fi, while for of us used it (just phone surfing) it barely worked. But I think, it's just temporary trouble. I would recommend this place.
