I had slept well in the two nights, and the neighborhood is pretty quiet at night despite being close to the main road (4th Ave). The room is in the back of main house facing the street, which took some time to find. It has the basics and everything I need. The hosts are welcoming and there's a little guestbook that visitors can sign.
It's also a 15- to 20-min walk to the beach in a pretty safe, walkable neighborhood. I used to live in Long Beach for a few years, so I'm familiar with some of the neighborhoods near the coastline. Thank you Robert and Briscia!
