The whole experience with Carles and his son was seamless. The apartment itself is situated within a 20 to 30 minute walk of almost everything you want to do in Barcelona. Taxi's and cabify run anywhere from $7 up to $15. There are plenty of restaurants, supermercados, and tobacco shops in the general area. The only suggestion I have is to include instructions in English on how to use the stove, the microwave, and the oven. We had to play around with Google and YouTube to figure it out.
