I have to preface: If I were staying here for less than a week, there would be one less star. But I stayed here for 3 weeks and when I consider the bigger picture, this place was near-perfect. I also stayed here in the height Summer, and secured a $79/night seasonal rate. For that price, this place is literally 5-stars! My only qualm is that the quality of my bed was lower than desired as I do keep a nice memory foam bed at home ;).
As a rule of thumb, Hyatt Summerfield Suites is my companies long-term corporate housing of choice in Scottsdale. They offer apartment like living quarters in a very central location. Service is great, and they have some unique amenities that make long-term housing a little easier: full kitchens, walk-in closets, sofa-beds for guests, weekday breakfast bar, weekday happy hours with apps, as well as the typical hotel amenities.
If you need to stay somewhere for 2+ weeks, and don't have an unlimited budget, consider Summerfield!
