Lower Unit. We stayed in the lower unit and the walls are thin so you can hear noise above and around you if you like to go to bed early or are a light sleeper. The host is prompt and does help with other guests if you’re having any issues. Just a warning to anyone who’s sensitive to this. The location is convenient to San Pedro, Long Beach and Palos Verdes if you’re exploring the area. The unit is moderately equipped and fine for a crash pad but, as with many air bnb’s not a great kitchen for cooking if you’re looking for that.
