Just stayed for one night. Very convenient to the Callao subway stop. Place is one block north of Calle Gran Via. Angel met me upon arrival and checked me in. Very secure entrance (2 locked doors plus house door lock). Elevator if you need it. Kitchen had basic supplies with stove top, microwave and large fridge/freezer - no oven. All worked great. One air con in the living room and one in the bedroom - will make the place ice cold if you want that. Balcony with table for two great for people watching of the little plaza below. Nice big bed. Medium firm mattress. Bathroom and shower all worked great with extra shampoo/soap/etc. Carrefour Express market 30 second walk from apartment well stocked with food, drinks, etc. Angel has a large map on the wall with dozens of local recommendations for restaurants and local sights. Very short walk to Plaza Mayor, Prado and other museums/parks. Would definitely stay here again!
