Well, it is true that Poble Nou used to be an industrial area, but, like the old industrial areas of many UK cities, it's now a residential suburb. The main street (Rambla de Poblenou) is a pleasant tree-lined stroll with a slightly cosmopolitan and very friendly feel to it. Plenty of cafes and resaurants to choose from, too. There is still some rebuilding in odd places - where isn't there in Europe these days? - but we didn't find it obtrusive or off-putting. There's a good bus service into the city centre that runs along the coast road at the bottom of the Rambla de Poblenou (our flat was on the Passeig de Calvell, right by the bus-stop). There is a Poblenou Metro station, but it's well away from the beach area and probably further than you'd want to walk with a small child. Nice walk along the beach into Barceloneta.......
