I stayed in Madrid the night before my flight home to the US. Carmen has a beautiful home, extremely close to Atocha station, and a 10 minute walk from the Prado park. She opened her home to me and had many happy tenants at once. The room was cozy and the wifi worked well. In august it was cool with the window open. Her cats are adorable and the cherry on top of a perfect stay. When I missed my flight, i was able to call on carmen for an unexpected stay, without booking through airbnb. She set up a new room for me and accepted cash payment.
