FJ's place is a solid place to stay in Santa Monica. The location is really convenient, the underground parking is a great perk, and FJ is really easy to work with. There was ample space for our group of six, which was great after spending two cramped nights in one hotel room.
Some people have commented on the cleanliness, and I would echo that the place could stand for a good deep cleaning and maybe a fresh coat of paint. It's also pretty spartan and not much in the way of "extras" that we've experienced in other places - board games, a robust supply of kitchen utensils, etc.
However if you want a reasonable place to sleep that's in a really convenient spot, and aren't overtlu picky on cleanliness. This places works great.
