4 of us stayed here for 4 days in August. Great location - 5 mins from the metro and 10 mins walk to sagrada familia. There are shops and a strip of restaurants located nearby.
The apartment was very clean and modern. The only issue was with the bathroom as the fan was noisy and was blocked up with dust. Also the sealant in the bathroom was a bit old/discoloured. This wasn't a big issue and the bathroom was clean.
Reception is located a couple of doors down. Check in was smooth and the receptionists were very helpful. Even booked our taxi to the airport.
The apartment is run like a hotel, so no cooking staples or extra touches that you often get with airbnbs.
There's a roof terrace to use until 9pm which is cool.
Overall, happy with the accommodation and service.
