This location is prime for any stay in the LA area. I grew up in Santa Monica and know the area well - staying in a room on Montana Ave you can just walk due west and there is great shopping there.
Given the prime location it is very, very quiet neighborhood, plenty of parking on the street, very safe no matter the time of day.
One tip is that the entry gate is a simple chain-link one accessed from an alleyway behind Montana Ave.
The room was simple and clean and the kitchen / bathroom / main room was nice.
