I loved staying with Carmen! She was extremely warm and welcoming which made me feel very at home. I stayed there for two weeks while looking for an apartment and she gave me space in the fridge and in a cubord for food and let me use the washing machine. As you can see in the pictures the room is small, but perfect for one person. The apartment is also very well located, a short walk from Retiro Park, the Prado and the Reina Sofía Museum.
