Sandra was a brilliant host. She was very friendly and informative and was quick to reply to all messages. Her place is in a fantastic location just off Gran Via very close to the Santo Domingo and Callao metro stops which made exploring the city very easy. The room was spotlessly clean and had pretty much everything we needed. Our flight home was at 9:30pm and Sandra allowed us to stay in the room until we had to leave for the airport because nobody had the room booked that day which was great because we didn't need to drag our cases around the city with us. I would highly recommend Sandra as a host and highly recommend her place to others. I would definitely stay here again if I returned to Madrid. Thanks Sandra.
