We stayed here for 3 nights and loved the amazing location! Great tapas places nearby like La Alcolba Azul and La Vinteria del Call and near sites like the Cathedral and Gothic area. We enjoyed our stay.
The apartment is a bit noisy due to Barcelona late eating hours, but that is a trade off for the superb location. Also taxis cannot drop you directly at apartment so you will need to wheel luggage from main road - it’s not far - we managed to do it with small kids!
