We loved our month-long stay in Montse's apartment and would love to return when we're next in Barcelona. The apartment was very comfortable, clean and functional. We cooked at home most nights and found pretty much everything that we needed. The apartment was plenty big for two people to live comfortably.
We especially loved its location above a small plaza, in a less congested part of the city. Most mornings we would walk the few blocks (and 200 steps) up to Montjuic to enjoy the beautiful parks, as well as expansive views of the city. And although away from the bustling (i.e., tourist-clogged) streets flanking Las Ramblas, the city center is easily reached by foot in 10-15 minutes. During our stay, we walked to hear music at various venues (including our favorite small club, Jazzsi), to watch films at the Filmoteca de Catalunya, and of course to eat many wonderful tapas (including at La Platilleria a few blocks away in Poble Sec).
Highly recommended!
