Miriam was a lovely host. She was accommodating with an early check-in time and the apartment was given to us very clean. The city was accessible as the apartment was across the road from Principe Pio station (if you take the correct, rear exit). However, we didn't need to take the train often as most of Madrid's tourist attractions are only a short walk away. I would stay with Miriam again. We stayed with 3 adults and 1 3-year old child. The 3-year old slept in the double bed with their parents. I slept in the other bedroom with the single bed which converts to a double bed.
