The Reserve is just condos for sale AFAIK. I used to live there when it was called Shadowridge Apartments. If they're renting, that'd be my #1 choice - great facilities and you can't get much further north. Just next door is Los Pinones Apartments. A friend of mine lived there with no problems. That'd be my #2 choice. Although, not in the North part of town, consider Rancho Vizcaya - they're just off of St. Francis Drive and would probably only add 5 minutes (or 10 minutes in rush hour) to your commute. For the record, Rancho Vizcaya is the best apartment complex I've ever stayed at.
San Mateo apartments are also
now condos for sale. That was the worst apartment complex I ever stayed at ANYWHERE let alone Santa Fe. I don't know if they're renting, but avoid it like the plague. The first week I lived there there was a guy stabbed outside my door. A month later there were gunshots... later came a full-time security guard and a horrible property manager. We had horrible problems with black mould there too. Those buildings are old - they actually found a way to polish those turns and sell them. Stay clear!
You should come into town a day early and look at all of these places. There's a web site where you can read reviews of apartments @ http://www.apartmentratings.com/rate/NM-Santa-Fe.html
. Take the positive reviews with a grain of salt - they're usually posted by the staff.
