This is a great apartment, easily accessible to La Rambla, Gotico and the Port. Drassanes metro line is just a few blocks away.
The apartment is up 4 steep flights of stairs, but there is a elevator so makes it easy to bring in your luggage.
The self-check in process was easy, and the Stay U-Nique team are very responsive to messages in the app.
I would definitely recommend this place for those visiting Barcelona for a few days looking to explore.
