Let me conclude first: this place is 120/100. Everything is wonderful, from the moment when you make an appointment (actually, even before that), all the way till the moment of checking out (and even after that).
The description of this place is very in detail on Airbnb, and there are many pictures that look exactly the same as the actual place. So you will get a very clear sense of what you expect;
After the successful booking, Hanh is super nice and very responsive, will get back to you usually immediately or at least within 10-20 minutes, this will help you to make your travel plan assured and you can relax;
The check-in detail is step-by-step with a photos guide. You will know exactly where you should park, how to get access into the room, etc. very clearly. And Hanh will also send you a message for check-in details and greeting you.
So the accommodation itself is also wonderful. The room is very clean and organized. It is cozy (since it's home-style decoration and furniture), and well equipped (with, for example, slippers, toothpaste, which are not common with other bnbs and hotels from my experience ). The private bathroom makes it even more convenient. The exterior environment is also very nice. It's a very quiet and clean backyard, there are couches you can use, and the swimming pool is wonderful (I didn't get a chance to play with it since it is late November so the water is a little cold, but it makes me want to come back again in summer). The front yard is also nicely decorated. There is every a small pond (with fishes in it) and a bridge over it!
In terms of the location, it's in a quiet and safe neighborhood, which is surrounded by tons of foods, especially Chinese foods like BBQs, hotpots, boba teas, supermarkets, etc. It's about 2 minutes (and 1 minute if no redlight) to the highway which will bring you to LA downtown in about 20 minutes. Also only 10+ driving to Pasadena, Chino Hills, etc. Very nice location.
The check-out is also smooth, and even after check out Hanh will send you a message again to thank you and welcome you back, which I really will do :)
So again, this is an excellent place and you will be satisfied.
