Yan-Yan was a fabulous host : Nice, considerate and very easy to communicate with.
Her flat is clean, well-eqquiped and located in a quiet residential district.
Easy to park on the street (with the park lisence provided).
If you want to visit Hollywood sign, universal studios or griffith observatory, think to anticipate time, cause these places are situated on the other side of the city and there is lot of traffic. But it's done easily.
Good stay, I recommand !
