The best I can say is that it's nearly impossible to find.
Located downtown right nellxt to the railroad track. Several trains a day go by, horns blaring each time. Not too bad except at 7am while trying to sleep. Easy access angled spoys, but narrow. Full service, 24 ft tow behind, 45$/ night. Friendly desk staff each of 3 times we've been here. Hot , full size shower is a nice perk. Picnic tables every 3-4 spots or so. I know there are homeless living around the area but have never seen them in the park. Fenced area with nice trees around. Almost wouldn't guess you are within walking distance of downtown.
For the location , trains , planes, and hard to fine. No cable. And TV looses picture when planes go over. Way over priced.
Noisy is right. And pricey - over $50 with discount. The park is OK but nothing special and weak WIFI. Over the air TV OK. The other downtown park was like a parking lot but $10 cheaper with cable. I'm staying there next time. Anchorage is hurting for RVs.
