We very much enjoyed our stay with Ana in Barcelona. The apartment was very clean, spacious and equipped with all we needed to feel at home for our stay. Ana even loaned us some of her family's toys for our daughter. The location was great too - a short (10-15 min walk) to Sagrada Familia, right on the edge of the Gracia neighborhood with many great restaurants and shops, and a quick (10 min) walk to the Metro where you can jet-set off to any of the other sights. There were also several playgrounds nearby which we used often to let our daughter spend some of that toddler energy. For her bed, we put one of the mattresses on the floor of the bedroom and it was not a problem for her at all. As other reviewers noted, there was construction going on from about 7:30am until 6pm each day which was certainly a bit loud - but this was not a usually a problem since we were out sight seeing all day anyways (and our daughter would just sleep in the stroller). It was very quiet in the evenings where we could even leave the windows open without any problems.
