This place is a gem in the heart of Mexico City. Both Enrique and the staff are friendly, hospitable, kind and very accommodating.
The venue is easy to get to (20mins from the airport). It is on the doorstep of the Mercado de Coyoacan. The neighbourhood reflects authentic Mexican culture. There is nothing pretentious about the area and in fact if you're looking to get away from the tourist traps and experience true Mexico then this is the place for it.
There are some phenomenal restaurants, taquerias and bars sighing walking distance. One must mention Casa de los Tacos - a phenomenal taqueria that you MUST visit. The prices within the area a that for locals (as opposed to inflated tourist prices) making staying at the mansion worthwhile. It is also close to the Frida Khalo and Leon Trotsky museums.
The place is impeccably clean. The grounds are constantly being maintained and there are 2 delightful and friendly dogs on site. The staff can arrange for a romantic dinner in the garden and they pull all the stops to make it memorable.
One cannot recommend Enrique's mansion strongly enough.
