I'm giving this place mixed review because for the money, the room was good. The main reason I booked this because the description mentioned "free parking on premises." That ended up being false and I had to drive around for an hour trying to find parking, only to move my car in the morning, then having to go to a paid parking garage the next day. I've talked with the host and she told me the parking comment was removed, but the whole experience was unpleasant and I missed out on work having to deal with the parking.
Another thing that bothered me was the hosts weren't wearing masks in common areas and the bathroom wasn't very tidy or clean. It felt like I was crashing in someone's home rather than staying at an airbnb with shared area. The fridge was messy and dirty as well. They have a dog that jumps on people and pees on a diaper in the hallway, adding to the unpleasant smells.
I tried to air out my room due to covid reasons, but the one window opened to a closed courtyard that smelled of exhaust, and the window didn't get any light. I chose to spend my time outside the whole day.
All that said, if you don't have a car (which is a horrible idea in Barcelona anyway) and are just looking for a bed to crash, this is a great space for the money. But not really a place where I would want to hang out and cook my meals.
