We stayed at Rocio’s place for 4 nights.
The apartment is relatively close to the Metro and so 10/15 mins from the centre of Barcelona.
There was plenty of space and we were comfortable throughout. Rocio was a great, responsive host.
The only downside for me is that I’m a light sleeper and the window/shutters in the main bedroom are very thin and don’t provide any sound insulation. I was woken up most mornings by noise from outside.
Otherwise, I’d definitely recommend!
