I am going to write about both positives and negatives. If I could go back in time, I would not rent this place again.
pros : location is good and the place is spacious BUt
- the internet in this place was a nightmare. super slow and totally disconnected at times. If you need reliable internet think twice before renting this apartment
- the apartment is very old. we were locked inside bedrooms multiple times since the doors were really old. The beds were also very old and uncomfortable
- the host was not polite at all. she said we left the house with "horrible smell" and tried to charge us extra for cleaning. this is despite the fact that we cleaned the entire apartment and never smoked etc

you have better options in Barcelona if you want to pay this amount of money
