This is definitely a great place for the price. Carol was very attentive leading up to my stay and worked with me getting in to LAX to make sure she was around to let me in. I stayed for two months and the place itself definitely has everything you need. The deck is nice to have and it's a very airy studio.
I initially was aiming to not use a car during my stay, but ended up getting one since it was much easier getting around South Bay and getting groceries etc, so I would definitely recommend having a car. However, it is walkable to the main street in Hermosa and a coffee shop/ restaurants away from the ocean as well. I am a software engineer so my view of this is definitely skewed, but I was working remotely from this house and the wifi could be very slow at times (1-2mbps). Again, I need a heftier connection than most people, but just something to keep in mind if you are planning on working remotely from here. Carol was helpful in trying to fix the wifi and seems to have plans to upgrade the equipment.
Overall, great place in a beach town with everything you need!
