The host was particularly nice and very helpfull! The house is nice, well furnished and amazingly clean. However, the heating provides some noise and one time you're cold, and 30mn you're hot (I don't know this type of heating in my country), as well as the wooden floor. It's a bit noisy when you don't go to bed at the same time as the others in the house. But it's not the case for everyone! And unfortunately, the train is very noisy from 4AM, it whistles 8 times for each passage. But I think almost every house from Mountain View not too far from rails can ear it! Take earplugs and it will be great :)
