We stayed 4 days in Donna's place and we do recommand this place. We haven't met Donna but every time we texted her or asked for help, she always answered very quickly!
The house was quite big and clean and not very far from the center (you still need a car in LA).
Plus, the wifi worked very well, we didn't encountered any problem with it which was a good thing if you want to look for good spots, restaurant, bars on the Internet !
The only thing that was maybe missing was the shampoo and body lotion but that was not very important :-)
We could come back here again !
