We stayed for a whole month at Mireia's bright and lovely flat! Gracia is a great neighborhood, it had everything we could want. There is a big market behind the building for farm fresh vegetables, lots of neat little shops, bakeries, health food stores and great vegetarian/organic restaurants as well as bars and tapas. Going in any direction there is something fantastic to discover, and the nearby plaças were magical.
The flat was kept very clean. Mireia is very tidy and cleaned the apartment often. But she was also laid back and didn't seem to mind at all if we didn't always tidy up right away after cooking.
The apartment looks just like the photos. It has a lot of charm and is decorated with really quaint flourishes. It is an older building but it's well taken care of. The flat is on the fourth floor with no elevator, but the stairs provide for good daily exercise! In addition to the dresser there are also hooks and a shelf in the room which really helps with storage, as well as a separate storage room we could keep our luggage in.
However, if you are a light sleeper be sure to buy earplugs. Barcelona is a notoriously noisy city and this street is no exception. It is worse on the weekends when the bars are open late, and people get especially rowdy when there is a football game on. My boyfriend is a light sleeper so he wore earplugs every night, however, I fall asleep easily but still had to wear them on weekends. The bed was comfortable, but firm. I had no issues with the length, I am 5'8", but Stefano is 6'4" so he had to put his feet through the bars of the bed frame to fit. But the bars were wide enough to accommodate so he wasn't very inconvenienced.
Overall, we would highly recommend Mireia's flat. She and her roommate were also very nice and gave us some good suggestions tailored to our interests. It is an adorable apartment in a fantastic neighbourhood and we were very happy with our choice.
