This location is pretty decent. Rambla de Cataluyna is a pretty central bustling pedestrian thoroughfare and is very accessible to the metro and you could definitely walk to locations like the Segrada Familia, the hip Gracia and St. Antoni neighborhoods, and the Gothic Quarter. The view of the Guadi home across the street and the Segrada in the distance was pretty neat.
The furniture and decor does seem a bit dingy and scuffed and are definitely a bit oversold via the professional photos in the listing. And in our case, there were not fitted sheets which was surprising and not ideal. I would also say that it's important to note that the city tax is not requested at the time of booking the stay -- it will be requested from you along with your passport details a few days before check-in.
Overall this place served as a decent homebase for exploring Barcelona, but there is room for improvement in terms of comfort, furnishing, and communication about fees.
