Great for business/pleasure trips
Definitely one of my top choices in Sunnyvale. I've stayed at it while on business trips and traveling with family. Good size rooms, comfy beds, tv/dvd, working internet, free water and welcome basket, decent breakfast, apples/cookies at frontdesk. Being on the road for much of the past several months, its these little things that make all the difference. Also their daily rates were quite reasonable.
Nitpicks - at breakfast they tend to run out of blueberry muffins quickly, also tends to be booked solid so last minute stays may be difficult.
