I spent 8 days in Barcelona with my family and everything was very good. The apartment is in a quiet neighbourhood and you can reach every destination that you want with the public transportation( bus or metro) very easily. There are also a lot of grocery stores and bakeries nearby.
The apartment is well-equiped with everything you might need ( to cook, wash your clothes, clean etc).
All in all we are very happy with our choice and we would recommend it to anybody who visits Barcelona.
