Bruno was a fantatstic host (plus: he speaks also french:) , really reactive and arrangeant. I was sharing with one friend / colleague and we had really a nice stay. This place is also perfect for a stay in family (3 minutes walk from Caltech).
The day I left, it was raining like crazy and Bruno offerered me a ride to Caltech to avoid being wet . Very nice. I'll stay at his place again, when I'll stay at Caltech
