I had the pleasure to stay with Calvin in Santa Monica. The place is center and very convenient to everything. I didn't have a car the first 2 days and there were many buses to travel with. Santa Monica buses are the best. Very nice coffee shop on the corner, new and open early. Calvin is nice, helpful and mind his own business. He is around, if you need any help. I had no issues with sleeping or anything. Overall, good host, smooth experience and definitely I recommend his place.
