I stayed at Ester's apartment for almost 6 weeks, and I was very happy with the place. My first reaction when I walked into the apartment was surprise at the large size of the living room. It is actually laid out as four distinct areas: the living space, the dining area, a reading area with a rocking chair, and an office with a great vintage office desk. The kitchen is fairly spacious, the bathroom has a good size, and the bedroom is in the back of the building, away from the street and very quiet at night. I appreciated my "silent nights" in Barcelona. The apartment is very tastefully decorated, and it felt definitely more like a place to live. I was able to do all my grocery shopping within a few blocks of the apartment (butcher, bakery, 3 supermarkets, fruit & vegetable store). The wifi was very fast; good enough for video meetings and cloud based remote work.
Getting around without a car was pretty easy with tow different metro lines in walking distance. I also found the area itself pretty interesting, even though it hardly shows up on typical tourist itineraries.
Ezio, who manages the place for Ester, not only provided my airport transportation, but also gave me invaluable tips for great restaurants and transportation options. He was super responsive whenever I had a question or needed some help.
Overall I very much enjoyed my time at Ester's apartment and would not hesitate recommending it.
