The stay was not good and I recommend to check other options in the city.
The check in with a digital key on your phone is a nightmare, full of technical issues and we got locked out of the flat at 2 am. Emergency phones number are not working.
The flat needs to be refurbished. Walls have scratches everywhere and every single door in the flat does not close or is broken.
The noise is very high as the flat is on a main street. At night you can hear every other residents coming up and down the stairs.
Better options are everywhere in Barcelona. We won't come back here.
