My wife and I stayed at this apartment with our two children in March 2017. The neighborhood in Roma is close enough to the airport and we felt really safe there. We were flying in for the first time to Mexico City late at night. Leo waited for us at the apartment to help us check in. He also bought some fruits and snacks for us so that we had something to eat when we arrived late at night. In addition to wi-fi at home, Leo also made available to us a mobile wi-fi device that we carried with us while exploring Mexico City. This was great because it allowed us to access internet while traveling in the city so that we can request taxis and look at google maps etc. We felt really safe knowing that we have a way to communicate even without a Mexican cellphone connection.
There are many restaurants and two big and nice parks close by. You can run or walk in and around the park. There are quite a few street food vendors around too. We enjoyed street food without any problems. The neighborhood is very convenient and safe and the apartment nice.
