OK. One must climb an exterior spiral stair from a courtyard to a third level apartment, but there you are on top of the world. One can see the mountains, the street, the morning sun, the big, big sky of Mexico City. It is a unique and stupendous 'sighting' of your situation in this wonderful land. If you like to walk, there are great amenities-- neighbourhood restaurants, excellent grocery stores, Felix Candela churches, old Coyoacan, and the National Cinema (25 minutes by foot) which is second to none in the world. Access to the metro is easy, but a 20-minute walk. The apartment is filled with light, the bath adequate and working well, the kitchen very nice. It's another world. Do it.
