We had a great time in Veronica's Loft. There is a large roof top terrace to stay.
The neighborhood looks quite save and around the loft you will find a few Oxxos, restaurants, a pharmacy, 2 theaters, a church, a public bath, 2 bakeries and a few smaller coffee shops. You can walk in 20 minutes to Condesa, to the Monumento a la revolucion and other interesting places.
The street is quite calm and clean.
The WiFi connection is quite good and fast.
I can recommend this place without any restrictions and would come again if I will return to Mexico City.
