We stayed at Hotel El Call for a few days to explore Barcelona.
The hotel always responded fast if there were questions and check-in and check-out were totally uncomplicated and also the staff was very friendly and helfpful.
The hotel is located extremely central - you can walk everywhere and there are lots of restaurants and bars to choose from. Our room was small but very clean (it is cleaned every day) and was equipped with everything you need. You should bring some ear plugs because sometimes there is noise from the street.
Overall I can definitely recommend this hotel!
