First, Carmen is a fantastic hostess. She is proactive with communication about arrival times and other needs and responsive to questions within a quick timeframe.
Second, the apartment and terrace are awesome. Being above the street level keeps the noise down some, and the terrace is a great place to relax if it's not too hot outside (evenings are beautiful!). The location around the corner from the Market and beside Calle San Jacinto is perfect.
You won't regret staying here!!
