Mires's apt is the best place to stay when visiting the city. It's centrally located, right in front of the renovated Sant Antoni market, between Raval and Poble Sec (underneath Montjuic). Purple and Green metro lines are close by as well. The apt offers everything you need, including airco and has a lovely terrace. The building has an elevator and is quiet at night, which is not always the case in Barcelona. In short, highly recommended!
