Really lovely penthouse apartment located on the Fifth Ave of Barcelona, near the Mandarin Oriental hotel and on the same block as the Block of Discord and Gaudi's incredible Casa Batllo. It is spacious and very nicely appointed. Our family of four (2 young kids) stayed for over a week and since we were a bit under the weather, stayed in more than expected. The apartment was great for us -- the kids slept on the futon outside (I found this very firm but the kids were fine) and we slept in the main bedroom. You can make both the bedroom and living room entirely dark with the blinds if you close them 100% of the way (took us a couple days to figure this out since we'd never seen blinds of that type) which was really helpful for us.

A few good things to know -- since it's like NYC's Fifth Ave, there's great access to shopping but it's less like a local neighborhood and the way the intersections are in Barcelona, it can be quite a hike to just go a few blocks to the corner grocer or a real grocery. Also there is a radiator or something that creates some air circulating noise in the bedroom -- I'd say most people could sleep through it as it's like white noise. Very little noise from the street since it's 9F up.
