Domènech i Montaner’s 1905 contribution to the Manzana de la Discordia, with Modernista carving outside and a bright, tiled lobby in which floral motifs predominate, is perhaps the least odd-looking of the three main buildings on the block. Since 2014 part of the building has been open to the public (by guided tour only – a one-hour tour in English at 11am, and 'express tours' every 30 minutes), so you can appreciate the 1st floor, giddy with swirling sculptures, rich mosaics and whimsical decor.
