Vicky's place is pretty amazing. It felt very cozy and the views from the bedroom are amazing.
You're literally minutes from the buses, metro and Barcelona-Sants Station (if you take the train in).
I highly recommend Vicky's place as a great get away.
Side note: we noticed a lot of shops are not open on Sundays but most of the tourist locations are open. The metro is super reliable as we didnt have to wait any longer then 8 minutes of a train.
