Kelly's place is great. It was quiet and a great place to get work done during the day. It is close to the Santa Clara Convention Center and there is a great taco truck two blocks away. If you are into running, the Alviso trails are very close and has great views.
I dont think there is air conditioning/heating (at least I couldn't find the controls) but the temp was great during my stay... I just needed the fan.
Overall, it was a great place and would stay again.
