Carmen is a very gracious host, and her apartment is beautiful and comfortable. She met us at the station from our night train, and took us to the airport for a very early flight home. As others have mentioned, she supplied us with much information on the city, provided a Transit card to use, and was generally very helpful and enthusiastic about her city. Add to that, little touches like welcoming chocolates, homemade plum liqueur and her beautiful smile, I would highly recommend a stay with Carmen. Language was a bit of a problem, as we don't speak Spanish, but we could work around this.
