It was a little tricky finding the place. For anyone reading this, the most likely route to the apartment is after you've parked at the Plaza de la Reina. Once parked head to the McDonalds and go 100m up the side street by the McDonalds (Carrer de la Corretgeria); Placa d'Ibanyes is a tiny alley on the left hand side and number 4 is a brown door 20m on the right hand side. Great location for the bars and restaurants - especially, San Tommaso (great Italian/Spanish restaurant) which is only 25m away. Relatively quiet despite being so close to the action. Very safe area.
