I would definitely recommend Tomoko's place to anyone who wants to enjoy BOTH quiet, comfortable stay and a quick access to all the fun that Santa Monica is known for. The location is just that unbeatable--5 mins to the beach and 15--20 mins to the pier by walk. It's fantastic.
The apartment itself is very clean, pleasantly decorated and the bed is really comfortable. The hot water in the bath is readily available as long as you first turn the tap water in the sink towards "hot" and leave it there.
I did not see Tomoko herself---only her parents---but all communications were very prompt and effective. They were very nice and enthusiastic people.
Again I would definitely consider returning myself if I may have another stretch of relaxing days like these.
