Curtis Park Club was perfect for our first trip to the Denver area. We were able to walk to Coors Field for Rockies games and one day walked around the RiNo area on a self-guided brewery tour. On our last full day, we finally took advantage of the bikes available, which I HIGHLY recommend--there are bike lanes on several nearby roads and it gave us the freedom to explore more on either end of town without worrying about parking.
On that note, we arrived at night and didn't realize there was no designated parking, and it was stressful to figure out first thing in the dark. BUT street parking turned out to be no problem. Most of the area has free two-hour parking during the day. Once we paid $7 to park all day in a lot on the main RiNo drag, and we went on several day trips so didn't need to figure out nearby parking those days. I do highly recommend a rental car because some of the drives are too stunning to miss.
Overall, I'd recommend Curtis Park Club to anyone. We were in room 9 (Enchanting Escape), which had a very comfortable bed and a nice roomy bathroom. ALSO there's a beer fridge upstairs in the main building with a constantly revolving selection of mostly local beer--and not just Coors! Great experience.
