The Arroyo Residences at 1250 Arroyo Way, Walnut Creek, California.

AVOID THIS APARTMENT. We called to apply for an apartment, they told us they had two available gave us a very nice quote, then had us pay the application fee. 2 weeks go by....no lease. We are out of town so we couldn't go in person, however, YESSICA and MICHELLE both assured us they will email the lease....2 weeks more go by, we continue to call and they keep saying nonspecific things like "We are working on the lease, you are definitely on our to do list" - I explain we have to arrange moving company to move our stuff to CA and we need to be sure we have the apartment...they dont care. 3 days go by, I call and say I need the lease today....no return call.
I found out the quote they gave me was too low and NEITHER of the TWO employees were authorized to give me that quote. We wasted over a month trying to work with them, ended up going with AIRBNB for a month because we lost out on two other apartment offers, then organized my move (for a higher price because of how last minute it was).

TERRIBLE CUSTOMER SUPPORT. BAIT and SWITCH.
