Due to cancellation and flight delays in the US I was not able to make it to Madrid in time to stay with Carmen. However, my sister made if from England and found the place to be clean and very conveniently located close to the Atocha train station. The accommodation was as presented: a room with 2 single beds with access to a bathroom. Carmen was very friendly and gave my sister a glass of orange juice in the morning. If you need a place close to the train station, this is ideal.
