We are a family of 4 (parent and two 12 year old twins) that had a trip to California (SF to LA). We ended the trip with 4 days in Manhatten Beach with where the goal was to enjoy the beach and have just a bit of sightseeing in LA (for the kids). The house is located at the north side of the beach, just a bit outside of Manhatten Beach scenic streets and houses. We had a car so the indoor parking was perfect for us. Beach was really close, so: (a) it was easy to just to get there and (b) we could hear the waves from the windows...
Location wise, there are some nice places (Wild Cafe) in a walking distance (other than the beach) but the real Manhatten Beach scene is located 7 minutes drive to the south (or 30 minutes walk - we've tried it); if you got the car, that's not an issue (Uber is $6-$7 each direction); There are some really good restaurants and gastropubs there...
The house is just beautiful, with a well-equipped kitchen large showers, very nice upper floor with Smart TV (Netflix) and sound system, which has a wide door where the nice breeze could enter. It also has a rooftop, however, we never used it because we only had time in the evening but the moist from the sea made everything wet.
The host is really great! was very communicative (but never bothered us), left us some snacks, milk, orange juice, sparkling water, and fruits. There is a Nespresso machine (very useful).
I could write many more things but really this is great!
