I stayed at Courtyard Phoenix North/Happy Valley for 2 nights in March 2011. I was traveling all over the Phoenix area, so I needed a nice, clean hotel not far off the interstate. This was exactly what I needed. I normally don't stay in suburban areas like this, but like I said I was traveling all over and wasn't at my hotel much beyond sleeping and eating breakfast. The hotel was very clean, the free breakfast was good (for what it is), and the staff was nice.
My room overlooked the pool area (which I didn't use), so it got a little noisy at some points. While this wasn't enough to bother me, you might want to request a room not facing the pool if you think it would be an issue for you.
There's just about every chain restaurant you can think of in the immediate area (again, this isn't something I normally look for), but if you want to go more intown it's maybe a 20 minute drive -- not bad.
I'd definitely stay here again.
