My wife, children and I Stayed at the hotel for 4 nights last month.
The location of the hotel is just the best, although the metro station 15 meters from the hotel was closed due to some work, there was just another entrance at the other side of the street.
You can easily walk to the main sites through the main blvd.
The hotel itself was great, we got 2 rooms with our kids and we share an outside garden which was directed to the back of the apartments around but was nice anyway.
Since the local breakfast is tea/coffee and pastries , consider if you like to pay 18 Euro per person for the hotel breakfast.... we were out every day and find many great coffee shops that has whatever you like for 15 Euro for us all... We will come back to this hotel for sure on our next trip to Barcelona
