I think i may need to look into this extended stay thing. I was dealing with some apartment community but they quickly lost interest when they found out I would be a new immigrant with no credit history or US income. I even offered to pay three months rent up front but oh well.
That was the issue we found, that the managed apartments were most legit, but also the most inflexible in terms of credit history etc that they wanted.
Re extended stay: To a large extent location will probably determine which you go for. The main ones seem to be :
Hyatt House (we got a good discount for a long stay, I can’t remember if it was 2 or 3 weeks that was the key for that.)
Marriott residence inn (said they offer discount but from what we saw didn’t really)
Extended Stay America (didn’t have one in the area we wanted so didn’t investigate too deeply)
Hilton Homewood Suites (ditto)
The rooms will be different sizes but generally they will all have some sort of living area and a decent kitchen. The bigger ones are like proper apartments. I think most offer breakfast and some offer free drinks/snacks a few evenings a week.
Bear in mind a number of these are aimed at business travelers, and tend to be on or near busy roads with easy freeway access. One minor exception is the Hyatt house in Seattle, which is a prime tourist spot right next to the space needle!
Again, get points if you go for one of these. We got straight to platinum status (as it was then) on Hyatt with our initial stay which gave us great perks at other Hyatts! (Free nights, room upgrades etc. all of Hyatt, Marriott and Hilton have a wide selection of hotels ranging from fairly basic to luxury.)
