We enjoyed our stay in Denis's apartment. It is a great central base to experience Barcelona. There is an enormous park nearby worth thoroughly exploring. It is also very close to the main street where many restaurants can be found, shopping is a 15 min walk down this road and a supermarket across the street made things very easy. I would note the 100+ stairs it does take to reach the apartment, as mentioned by other guests, it was not a problem for us and it's worth it to reach the top for a great view from the balcony.
