My stay with Sergio was excellent. The location in Long Beach is very convenient and right off the 405 and Pacific Coast Highway (PCH/Hwy 1) so no matter where in the South Bay or LA proper area you need to go, it's simple to get there.
The room itself was quaint and had the basics you need to be comfortable. Sergio's home overall was very clean and well-kept, plus if had a nice "cozy" feeling like you're visiting a friend, not staying with a host you've never met before.
Sergio was incredibly responsive, communicative, and welcoming; I look forward to staying with him again. I will absolutely advise friends looking in the Long Beach area to stay with him as well!
