Em was super helpful, and made us feel right at home. We definitely felt like the (very big) space was our own, and we thoroughly enjoyed our stay. We were both pretty knackered after a solid few months work in the Alps, and the space was perfect for us to relax. The only thing I might suggest for light sleepers is some ear plugs, as the street outside is quite lively until about 1am. It's not noisy like loud bars or clubs, rather peoples voices and talking in the various excellent tapas bars down Carrer de Blai. The flat itself is easy to get to from the airport, and it only takes about 10 mins to get to Ramblas. There's also a bike rental place super close to rent bikes from if you want to get around the city like that. Overall, a great space with a great host who also very kindly printed out our boarding passes for us.
