The place is close to the Hostafrancs metro station making it super easy to reach places in Barcelona. We only stayed one night but we felt comfortable and cozy inside. 3 bedrooms, one of them is a suite + 2 others very small with 2 wide single beds each. Pillows comfortable. Mattresses could be better but they did the job for one night. The staff (Alvaro and one of his colleagues) was super helpful: they were easy to reach, helped get the luggage up with the elevator (one suitcase per escalator trip) and they helped us book a cab for the next day to the airport, relieving us from a lot of stress. The place is well equipped and was clean (except the couch). Plenty of restaurants around making it possible to have a quiet and enjoyable night in the neighbourhood. The insonorisation could be better: we heard loud noises every now and then from the street as if happening in the apartment, we can hear people going up and down the stairs but it’s OK. One thing that bothered is the smell of weed getting inside the apartment (we had babies) despite everything being closed.
All in all, I recommend the place :)
