Recently stayed for two days at Candlewood Suites for a business trip. The room was about what you expect. The only real complaints were that the AC unit exuded a cigarette smell (easily cured with a Lysol spray) and some of the television channels were pretty fuzzy. My partner said his TV only received a few channels clearly, but he didn't really watch much. The bathroom floor could use a cleaning with bleach.
The hotel as a whole is clean, has an honor-system "Cupboard" with snacks, frozen dinners, and drinks that is combined with a free laundry (accesible with the room card), a pool and hot tub, and an exercise room.
The location is a bit of a problem as it is on the I17 frontage road. This means that north is the only direction you can go when leaving. To go south, you have to go north and back to the southbound side. The "Enter" sign is small and is obscured by landscaping shrubs until you are just at it. However, the hotel has access to the biking trail of a city park, which means that taking a walk for exercise or fresh air is just a matter of walking through the pool area and out a gate.
Aside from traffic noise from the Interstate, it was pretty quiet. There are signs up all over announcing a renovation project scheduled to start in December 2011. The kitchenette was clean and had just about everything you might need in this sort of room.
Comparing Candlewood to the business suites just south of it, Candlewood is the much better choice.

I called ahead approx. 2-3 weeks and booked the room. The staff member that I spoke with was friendly, informative and accomodating. I arrived here in Phoenix the middle of August. The check-in was seamless and the woman at the front desk very pleasant. She called after about an hour to see if I had everything I needed or if she could be of assistance. Good business! Not sure how old this hotel is, but the owner's have done a nice job in keeping it fairly well updated and very clean. I recently heard that they are going to go through and do an upgrade! I had one issue with noise, but it's due to circumstances they can't control. The location of my original room is right between the stairs and the elevator. I didn't hear too much noise from the elevator, but every time someone went up/down the stairs (and it was often!) it sounded like a herd of elephants coming through my bedroom wall and ceiling! I am a night worker/day sleeper and you can imagine how little sleep I was getting...even with earplugs shoved into my ears! I liked my room and didn't really want to move so I tried sleeping in my living room on the sofa. No go. It was still way too noisy! The desk staff were VERY accomodating and moved me to a different room. I was able to stay on the first floor (my preference) and keep my poolside view! Very nice. They gave me ample time to move and didn't rush me. I'm extremely satisfied with my new room AND the manner in which it was handled! Maintenance is very knowledgeable and quick to respond, housekeeping is excellent as well. Can't say enough good about the front desk staff, too. I will definitely recommend this hotel to anyone I know and will stay here again without hesitation!

I have stayed at this property a few times during my trips to Phoenix. Location (next to I 17) is a big plus.
The front desk staff is helpful. It is moderately priced, especially for extended stay though the property is a bit older.
I would recommend this for a no-frills extended business stay, especially for those looking for a kitchen in suite.

Handy to I17 and good check-in. Fully equipped kitchen and lots of channels on the TV.
However . . . I found the bathtub tiny (could have easily been a little wider and longer . . . lots of space). Also, the bath towels were like burlap!!
