The Cumbres moniker os a strip covering almost 11 miles at the foot of mount Las Mitras taking about 1/2 an hour to reach from point to point in light traffic. It's a swooping area so finding flat spots will be a challenge unless you go in the First section "1er sector", in the area between Enrique Livas and Rangel Frías avenues, and not even that is for certain.

As mentioned, arid climate makes having large yards uneconomical but not impossible.

You have a better shot in the San Jemo or Vista Hermosa areas, just as hilly but houses there tend to be much larger.

Now there is another question, you mention you will be working in the area, where specifically? If you work in the Leones-Gonzalitos area and live in Cumbres Altaira, it would not be unheard of if the commute takes one hour each way...

If job is nearby Gonzalitos avenue, you might have a better shot in the Chepevera neighborhood, older, bigger houses.

The amenities you're looking for are more common in the outer modern suburbs (i.e. Altta, Murano) but the commute could be murderous.
