I stayed at the flat for 5 nights, mix of work/vacations, the communication was very good, the flat is very nice, spacious, and clean.
The kitchen had all the necessary appliencies for cook and have a good time.
Also, the area is super well connected, there are plenty of places to eat and supermarkets around, very safe in general.
And the bonus is the shared upstairs area, where you can enjoy the end of the day having a view of Barcelona.
