Sarah's place had a very bright, pleasant and cheerful style. It was very clean and fully equipped with all the things you could need (including things like salt, sugar, coffee and tea etc, which are often missing in airbnb places, and always appreciated when they are there).
Sarah was flexible for our check-in and check-out, and we were very grateful for that. She was also very forthcoming with her communication with us, and we felt that good preparations had been made for our arrival and stay.
We didn't want to stay in the centre-centre of Barcelona (a bit too busy for us), so this flat was perfect. The area where it is located has nice places to eat and it is literally just next to the metro, so that was great.
I would definitely recommend.
