This place is a great location. It's near Sagrada Familia and walking distance from Gothic quarter and the bus station. The metro is right in front so grea location to get anywhere.
The check-in and mobile access was finicky and you often need to stand there for a while and try a couple times to get it to work. I suggest if you have time go get the key or if you don't mind just try a couple times.
Heads up, we had a major issue during our stay because right next door they are doing construction from 10am - 5pm renovating the place. It was a big issue for me and my roommates as we were expecting to be able to work from home as remote workers but we had to find other places to work during our week there. It was loud construction with drills and hammers, so if you plan to sleep in or just be able to rest at home between those times whenever you want, this is not the place for you. But if you'll be out and about during this time and don't mind, then go ahead.
I would recommend it if you just need a place to go for the night, but I would never come here again. The whole handling of our issue and accomdation was a mess and instead of relaxing we were scrambling to find some way to work this out.
