Although we did not have the pleasure of meeting Mario in person, he made himself extremely accessible by phone. The location is quiet, and we felt safe the whole time. There are some great restaurants nearby that Mario recommended to us, and the subway is just a short walk away if you want to explore the city. The apartment was very clean, well decorated, and gets a lot of sunshine. It's a great place to relax. I would definitely recommend Mario's place to anyone visiting the city.
