Angela is the best host you could ask for. She is very kind and willing to do anything to make you feel at home.
The place is very clean and confortable.
Regarding the location, I must say that LA is a very big city and the sighseeings are located in different parts of the city. If you have a car, Angela's place is no more than 20 minutes to most touristic sites (apart from rush hour). If you don't have a car, Angela's place is around 10-15 minutes walk to a train station that can leave you anywhere in the city. Or you can take the bus to the station, although their timetables are not very user friendly. I didn't mind walking, so for me it was a perfect location. Lift is also a good option.
I must add that Angela's place is located in a residential neighborhood. For me it was good because it is a calm place and you feel safe walking around at any time (I didn't see any homeless people around there, compared to the many I saw in most parts of the city). But there are some restaurants and markets 4 blocks away if you need anything.
That said, I strongly reccomend Angela's place, and I would definetely go back there.
