A true Spanish original, this long-established shop located just a stone's throw from the Puerta del Sol sells nothing but guitars. Not any old guitars, though. These handmade gems are purchased worldwide, and all shipping orders must be placed in the shop itself. Such is its fame that experts past and present, from Andrés Segovia to Dire Straits' Mark Knopfler, have had their guitars made here. You can also visit the workshop to see these instruments being made on weekdays. Open Monday to Friday 10am to 2pm and 4:30 to 8pm, Saturday 10:30am to 2pm.
