The apartment was small but perfectly functional et well designed. It was also well located, about 30-45 minutes from main sight-seeing spots (15 min to Güell Park), which I thought was decent. Very good restaurants in the area as well, so no need to go far to enjoy food and wine! Also, Blanca was easy to reach and accommodating (we checked in earlier than planned). The place was very clean as well.
You should note that the water in the bathroom can take a long while before heating up, which was frustrating at times. Also, there is no AC and it is very sticky in the apartment at night; 2 fans were provided which helped most nights, but on very warm days, we had uncomfortable sleep. Finally, the stove works with gaz and you need to manually lit it, which we were not comfortable to do with the oven, although we did manage to use the stove top few times.
