We were not happy with our stay because we arrived after 24 hours traveling with kids and the building was under renovation. The apartment had a huge noise and we were not able to sleep after our trip; then at 8 in the morning they continued the works. The noise was during all our stay. The owner was not very communicative because we asked some amount of refund for the huge inconveniences but she refused.
Also, the apartment was not very clean: dirty blankets, pillows that have holes; smelly towels. The dishes were not very well cleaned, taking into the account the cleaning fee is not a small for this apartment. Mold in the shower.
The location is not the best, even though you can walk to Sagrada Familia and Park Guell, the street itself smelled like urine.
We wouldn't come back to this apartment.
