The location is ideal. Just 3 minutes to the Prado museum, 5 min to Retiro park (very nice), about 10 minutes to main squares Plaza Mayor and Purrta del Sol. Easy to get to Atocha station if you plan to travel to Toledo and Alcala de Enares (highly recommend). Flat is clean, all what you might need is available. Marta provided all useful information about shops, restaurants, gave tourist maps, answered all our questions. We had great 6 days in Madrid and in Marta’s flat.
