We had tickets to see the Last Supper and Carla was very accommodating to our check in time needs, and even when we got delayed on the train Greg waited for us and then called us a taxi after check in to help get us there on time. The flat was just as described and while it is small, it was just enough for what we needed for a place to sleep. The location is super close to Duomo, shopping and restaurants that are a 5 min walk.
