Just spent a week at Oceanside from August 10-17th 2006. I must admit, after reading many negative posts I was not sure what to expect.
The unit was clean, well-stocked and in good working order. The noise from the train was almost unheard IF your door was closed and fairly loud if not.
Several pointers for those not familiar with the area:
#1) There is a small mini-mart that carries a variety of food, fruits and veggies within walking distance. It is just over the large bridge the resort sits near.
#2) The beach is out the front door, take a right, down stairs, cross the parking lot and thru the tunnel to the harbor. Continue past the harbor and tourist shops to get to the beach. It is about a 10 minute walk.
#3) Most (if not all) of the tourist shops and restaurants at the harbor (see #3 above) have a discount coupon of 10-15% available in the resort lobby.
#4) The Coaster, Amtrak and Metrolink station is about a mile away. The Coaster is the easiest way to get to Old Town and then hop a taxi to Sea-World. One way ticket price was $5.25 plus the taxi from Old Town was about $15. Coaster does not operate on Sundays. All 3 go to Anaheim to get to Disneyland. Taxi from Anaheim was about $10. Amtrak and Metrolink operate earlier and later than the Coaster (plus Sundays). Cost was about $15 per person (kids 1/2 that).
#5) The Staff at Oceanside was AMAZINGLY helpful.
#6) 2 Computers with a printer are available in the lobby for your use (IF, and I say a BIG IF, you can keep the teenagers from hogging them for their MY.SPACE addiction. No, that's not an exaggeration!)
#7) The gas line for the grill is turned off directly behind the grill. You need to turn it to use the grill.
#8) Harbor tours, fishing trips, whale-watching trips, and shark fishing trips are all available at the blue corner building at the harbor cat-walk. There is a discount coupon for all but the whale-watching trips in the resort lobby.
Hope this helps save you some time and head-aches.
