The apartment was clean and pleasant. But please be aware that if you suffer from athsma or allergies this might not be suitable for you. There were four of us staying, and two of us have mild athsma, but the air in the apartment made me sneeze uncontrollably for two days, and the other athsmatic guest had headaches and we both needed the use of a blue salbutamol athsma inhaler regularly. I also bought some antihistamine tablets from the pharmacy next door which reallt helped too, as did washing the bedding and keeping the windows open for fresh air.
However the other two guests were completely unaffected by the air in the apartment.
The location was good and there is a small bakery next door, a nice restaurant over the road, a pharmacy and shops nearby, and a bus stop right outside which takes you to the city centre regularly and takes approximately 35 minutes. The host was very helpful and welcoming, and spent some time showing us a map of Barcelona and showing us how to get to the main attractions.
