Location: perfect, close to SFO, walkable to BART and Millbrae downtown.
Room: it's pretty much everything.
Bottom line: it's perfect for business travelers, got everything you need, close to airport. and millbrae is convenient to go to SF or South Bay. It's parking spot so it's a plus too. And I think it's priced precisely so it's really great for the price you're paying.
My only dislike is I don't like turning on fans and I want to open windows for ventilation. But if you do, the occasional train and plane noise could be disturbing, particularly I'm traveling from Asia with jeglag which made my evening a bit sensitive. I eventually closed all the windows but then it got a bit too hot and stuff. Other than that, I think it's great. Would like to come back again.
