Although this is one of the nicer Extended Stays that I've stayed in, it really needs help. And I don't think the sort of help it needs will come via its current practice of placing placards in the room giving instructions and asking that everyone give them 5 star reviews on TripAdvisor.
The rooms are quite spacious and modern with added amenities like full kitchens, large flat screen TVs and DVD players. But they are not maintained with any consistency. They also offer a shuttle service to the airport (on time and friendly), to the light rail and other places nearby. I stayed here two different times in one week, with very different experiences. Inconsistencies were things like:
No mattress pad on the bed, where I could feel the mattress labels right through the sheets.
No dishrag in one kitchen, no drinking glasses in another, no kitchen clock in one.
One room had a nice quiet heater away from the bed, another had a loud broken one right next to the bed.
One room had a continually leaking/dripping faucet, another had a shower curtain that you actually stood on in the tub because it had been positioned so low.
In both rooms I had the unpleasant experience of the alarm clocks suddenly going off. I don't think its too difficult to train housekeepers to check that these are turned off when cleaning.
There were burned out light bulbs as well, which I went to the front desk to exchange.
The front desk help while friendly, displayed a surprising lack of follow through. There were two phones in my room, neither of which worked. I had to make a rather long trek to the front desk in order to report it, and they told me that they had made some changes. I was told to go back to my room and they would check with me (by phone) to see whether it it was working in two minutes, and if not they would send someone to my room to repair it. The phone never worked, of course I received no phone call and there was absolutely no follow through, so I just gave up on it.
So if you like taking chances and can deal with disappointment, this is a great place to stay. You just might luck out.
