An ideal place to stay in Madrid. Nice host, very central, close to metro, surrounded by restuarants, clean room, towels changed daily and reception open 24 hours. Using this hostal as base one can visit the main highlights of Madrid just be walking to them - Plaza Mayor, Cathedral, King's Palace, Prado Musuem etc. Not to mention that the main shopping streets are only minutes away! The only negatives are sometimes noisy people in the street below who do not seem to sleep during the night and the small room. But otherwise Hostal Esmeralda is a good choice to stay in.
