Cristina is a fantastic host. She was very helpful in showing us how to get around on a map and giving us restaurant recommendations. We also really liked the area we were staying. It's a charming neighborhood that's less busy than the center of everything, but it's very easy to walk or take public transit (I recommend walking everywhere once to see the city and then taking public transit back). It also has plenty of delicious restaurants right in the area, as well as a couple of grocery stores and cafes on the same street. There is some noise from the street, but we use a white noise machine when we travel, so it wasn't a problem for us. We had a fantastic stay!
