I had a good stay at Constance and Mike's place. The room was very clean with comfy bed and good windows. The house has a lot of interesting touches.
Their condo is about 10$ Uber ride to Convention center and the top attractions of Long Beach near there. It's a 2 minute walk to Anaheim street, which I found out by accident, that has a bunch of interesting little Asian shops.
Mike and Constance are sociable and Mike was nice enough to share his knowledge of the area with even gave me a ride to a local spot.
Communication was fast and excellent.
