I had a great experience at Garden of the Gods RV resort. They must have changed owners or management in the past year because the older reviews I saw weren't as glowing.
The park was clean, staff was helpful and friendly, there's 24 hour laundry, showers, electric and sewage hookups with a general store and food truck in the mornings.
It was easy to walk to downtown Old Colorado Springs and there's a free shuttle that'll take you to Manitou Springs. It feels safe even as a single female camper!
