The room itself was as described - it's a decent size with plenty of natural light to boot, and it features a great view of the hill across the street. The bed was comfortable, and the desk was great for organizational work.
What surprised me the most about this listing and the SGV was the PHENOMENAL view of Mount Baldy and the S.G. Mountains (from down the street). If you can go for a walk on a clear, smog free day, it’ll look incredibly picturesque (and frankly surreal). I also loved that Diamond Bar felt different enough from Central Los Angeles to be considered as its own area/city; and the more laid back, more friendly atmosphere.
The things that made my stay worthwhile were the family dog, Doudou (she's really sweet, friendly, and playful); the family cat (I adore her); and the generally laid back nature of Renee and her family. Renee doesn't speak much English, but tries her best to communicate well with you.
I enjoyed my stay, and would consider staying again. Thank you!
