To clarify and expand upon Snorkdoc's post:
1. About half of this hotel's rooms do indeed face an interior atrium, but they are pretty well soundproofed, so unless there is a party of some sort in the atrium, you won't be disturbed.
2. Half of the hotel is brand new; it was formerly an office tower that was gutted and turned into additional rooms. Those rooms are all new, though rather sterile.
3. Contra Costa is a county in Northern CA. I think he/she meant to say Garden Grove, which is the city where this hotel is located.
For $27 (plus about $10/night parking), you have an excellent deal in a very nice hotel. Enjoy.
