Donna is a very good and helpful host. As of the place - it is very well located in Santa Monica, approx 2 miles from the Santa Monica Pier and 2 miles from the Marina. 5 minutes walking to the beach - however we were experiencing pretty bad smog, so we had to go to the beach to Malibu to have clean air :)
the promenade along the Pacific cost closeby is very cool and extraordinary. It's great that the place has a private parking spot, as you need to pay everywhere for the parking in L.A. Donna left very clear instructions for check-in and check-out, which I appreciate a lot. The apartment was clean and neat, all you need is there - kitchen, fridge, coffee machine, utensils, even beach towels.
I would recommend this place for sure.
