Excellent value, great location for those staying north of downtown
If you need affordable lodging on the north side of town, you are unlikely to do better than than the Sheraton Crescent. Situated along I-17, it was a surprisingly full service property offering reasonable rates. SPG members will appreciate the club lounge and reasonably fast WiFi. Their gym is much larger and better equipped than most Sheratons, and open 24 hours. 
The pool area is quite large for a business hotel, with a swimming pool, hot tub and large water slide for the kids. My niece and nephews were very enthusiastic about the slide, so I'd have to say the hotel is very kid-friendly. The only downside is that it is locked and requires hunting down a staff member to let you in to the water slide pool. 
High praise for the friendly front desk staff.
