There are several ways to find out about rentals around Galisteo St. area, the best way is to do your research on line as you suggested or try some of the property management companies in town such as Vista Prop. Management, Kokopelli Property Management, and or Casas De Santa Fe or St. Clair properties. All of them are fine choices for your research, also are you looking for a vacation rental or a short term rental or long term, furnished or unfurnished. Then you can determine your market and price per square foot for a rental in Santa Fe, down town market which is going to be higher than other area especially if your are in walking distance to the Plaza which Galisteo street can be depending on the address of the property.
