Well located, mid range price (reflected in internal fitments and what is supplied etc), great cafes a short walk away, metro just outside but most things also walkeable, great check in check out process and electronic keys (much more convenient than having to pick keys up from an office), well ventilated flat 2 bedrooms and both bathrooms have windows that open onto an internal air shaft which runs vertically the height of the building (a great bit of design that provides ventilation and keeps air cool, road outside a bit noisy but only noticeable if both balcony doors are open, good shutters and black out curtains, balconies to living room and master bedroom.
Would definitely recommend as a base for exploring Barcelona
