I liked the location (next to shop, parks, museums, Aldi supermarket, etc.) and walking distance to Plaza de Cataluña and Ramblas. I loved that it had an elevator, a washing machine inside the apartment, A/C, and good WiFi.
The apartment wasn't bad, but it was not the apartment that I reserved online. It was very similar, but not the same. When I pointed this out to the person who gave me the keys, she said all apartments in the building were the same and the differences were minimal. This particular apartment had a broken closet, but the agency refused to reimburse me for the inconvenience. Other than that, it was a good place to stay.
