Overall great!
Extremely central location under a 5 minute walk to Plaza Catalunya and looking over the Casa Batlo. Proper amenities, separate bedrooms and two bathrooms, with a small outdoor space
Check in was a bit of a hassle, you have to open the door by internet, which is an obvious problem because the building doesn't have wi-fi on the outside. I had to find wi-fi outside in the street, while my friends were tugging at the door
The appartment isn't the newest, there are some signs of wear, older fittings etc. but everything works, everything is clean and the kitchen has the essentials
Overall, very happy with our stay and great value considering it fits 4 people with no discomfort
