This is one of the few places on here that is better than the photos. It's modern and cozy. There is no elevator in the building but it's on the first floor. Stairs are narrow though. There is a nice little balcony overlooking a beautiful church and a square.
The area is in the old gothic part of town. Right off the La Rambla and a couple of minutes walk from the metro. There are lots of cool stores and cafes nearby, and if you're into coffee there is an excellent place called Satan's Coffee Corner.
The only issue with the apartment was in the shower. It leaked lots of water into the toilet floor after a few minutes. It was annoying to have to mop the floor after every shower. We mentioned this to the host and they have it fixed soon. Oh and if you are a light sleeper you won't be getting lots of sleep. The street noise feels like people are in your apartment. And it stays till the early morning hours!
