Do not be misled by the images. This unit is a studio with two single beds and a rather uncomfortable sofa bed (very thin mattress).
It is well located near the Sagrada Familia; however, other attractions are far if you plan on seeing the city by foot (45 min+ walk).
The place was clean and had good air conditioning, but be mindful that the check-in process is not flexible, and you MUST arrive by 7 pm (which can be challenging with post-pandemic travel delays).
Considering prices for hotels/rooms in Barcelona, this was good value.
