I stayed at Diane's place for 4 months while working at UCLA. The experience was perfect.
The studio is right next to the Santa Monica Pier. Its in the heart of the tourist area of Santa Monica, so if you are visiting and want to see all the attractions then it is a perfect place for you. The space feel so much bigger than it looks in pictures. The bed is very comfortable and the kitchen with stove/oven/microwave is a great amenity if you are planning to cook. They also have dedicated parking if you are bringing a car, which is essential in the area.
Diane and her husband were great hosts. They live in the space right next door and were so accommodating. They always responded immediately to all my questions/concerns.
I couldn't have asked for a better space/host. I would not hesitate to stay here again in the future.
