I highly recommend renting this apartment! We absolutely loved the place!! It's exactly as shown in the pictures, everything was so well put together. It's located near to the tube and one of the biggest tourist attraction, Sagrada Familia, which is a plus. I would definitely stay here again when I visit Barcelona.
Juan was also very helpful, telling us what to do and eat around the city. He was also very flexible with our check in and out timings which was great as our flight was delayed. He was also easily contactable and answered any questions I had very quickly.
Overall, an extremely pleasant and great experience!!!
