This motel is very good value for the money.
We stayed 6 nights in first floor room 8, one king size bed. Room was always clean, it has all nesessary basic things. Bathroom is very good, lots of space on table to put everything there. People we saw in front disk were very helpful and nice people.
It is true, there is some noise, because Main street is very near. But I think it is good thing, because it means, there is lots of good restaurants and bars in walking distance. And we had so much to do everything on daytime, that when we finally went to bed, we slept immediatly !
If you want to walk to places, this is for you. For example, SeaShore Motel is one block from beach. You can walk to Santa Monica Pier, to Venice beach, and there is easy shuttle you can go shopping to 3rd street. Good way to move by beach side is to rent a bike from the beach, there are several places. We rented tandem, very funny way to move.
For this price (about $110), I am certain, there is no better deal in very popular Santa Monica.
