This is a great space! The front rooms especially are great--nice natural light, etc. The neighbourhood is walkable and there are grocery stores, etc just a couple of blocks away. We also regularly walked to the Arc de Triomf & Gothic Quarter, etc, though if you are not a big walker these might feel a little far.
My only complaints are that the WiFi isn't strong enough to make it to the front bedroom. If you have international data (we did), this is not a big deal, but annoying if you are planning to depend on WiFi or if international data plans are cost-prohibitive. Also, I wish I'd known before booking that this is NOT an individual--you are renting from a company called BizFlats who will send lots of emails, etc.
Overall, though, this is a great space and we would definitely stay again!
