Mireya is awesome and really quick to reply back to any questions. Her building is building 3 and located on Calle Hamburgo and Av Insurgentes Sur. We were a little confused when we first arrived and because we can hardly speak any Spanish. Once we did find the entrance the front door people were great. The spot is perfectly located and I highly recommend buying the city bike pass. It was a lot of fun to bike around to the museums and restuarants. Also the apartment is really close to a bike spot. Oh and there is a jacuzzi! Yeah! It's near the gym in one of the other buildings, you can get there through the common space. They also offer massages... I think it's 10 dollars for 15 minutes!
