We stayed in the apartment for 2 weeks in July. We liked the apartment; it was very functional, well equipped with big closets, confortable mattresses, a small but functional kitchen and a nice and spacious living room. All like shown in the photos. In addition the apartment has an indoor terrace very helpful for extra space. However, I have to say a couple of things that we didn't like such as the noisy road outside ( not affecting the bedrooms at all), TV not working and above the bad smell outside the apartment (stairs and common area) with a couple of cockroaches.
The apartment is located in the Left Eixample with a very friendly and nice portuguese coffee shop next door but this area is not the nicest one. For a nicer neighborhood you might want to consider streets closer to Paseo de Gracia.
