Noemi's place was spot on! Nice, clean, and offered everything and more! I felt welcomed on my first night by meeting her and the family in person. Granted I was out during the days for work a few blocks away, but the mornings and evenings spent in the home and walking around were excellent. So can't speak out about working from home if construction or other things are happening in the neighborhood during the day.
If you're working in the downtown Sunnyvale area, no need to rent a car. Many things are within walking distance and felt safe through out my stay! Will definitely be coming back on my next business trip for sure! :)
