Location: Excellent!!! especially if you want to spend a lot of time at the beach. The proximity to the Venice canals, interesting restaurants, and thrift shops is a bonus. We had to meet people in Brentwood, Huntington Beach, Glendale, and went to Disneyland so the location was useful for us.
Sound: Yes, there is a guy who loads and unloads LIME scooters around 4am with the associated truck sounds. My family are all deep sleepers and go back to sleep easily so this was not an issue. I met the guy one morning and he was very nice. If you are a very light sleeper and cannot go back to sleep once woken up, you may want to think twice.
Parking: There is a lot of parking on Pacific Ave. however across the street on Monday mornings and on the side of the street where the unit is on, on Tuesday mornings there is street sweeping. Also, across the street there are a lot of areas it seems one can park but watch for the faint red painted curbs, albeit they all have "No Parking Fire Lane" signs somewhere. There is some parking past Washington Street near the Anchorage Street School which restricts large trucks. On one Monday evening, I found my spot there.
Unit: The unit is not fancy but it is very well kept and the host is very responsive. It is excellent value especially for the location. My family liked the coziness of the unit. All the amenities are there and my daughter even made pancakes one morning from the instant mix leftover from other guests. Shampoo, conditioner, toothpaste, plenty of toilet paper, pots, pans, all that. We happened to be there when it was unseasonably cold. The furnace does work but you since cold is not usually the problem in this area, you may want to know how to light a pilot light or ask the host who will be happy to instruct you.
Overall: Just a really great place. You can't beat the location. Some other AirBNBs in that area have cats while this one doesn't which is good if you are allergic. The host is very responsive. What you see is what you get and this is excellent value.
