This apartment was ideally located for our 3 day discovery trip of Barcelona.
The best part of it was an amazing view on the Sagrada Familia from the large terrasse, where it was great to have a drink or our take away after a day trekking the city. No restaurant offers such a view ;-)
The flat was clean, quiet, very easy to access with the elevator.
Alonso and his colleagues at Stay U-Nique were always available, friendly, and quick to answer all our questions.
If you are looking for a base from which to explore the city, and to come back to and relax on your own private terrasse in the evenings, I would highly recommend this apartment.
