Yes, stay here! Location is everything. The apartment is basic and comfortable, but you're gonna wanna stay here if you spend most of your time outside, staring at the ocean!
Things I'm really glad I brought to this AirBnb: yoga mat for doing daily yoga on the beach, bike for riding along the beachside bike path, coffee and filters (there was a Keurig with no pods and a ceramic cone but no coffee or filters anywhere), earplugs (street noise is incredibly loud, central air/fan creates a maddening, incessant rhythmic hum). Things I had to run out and buy while i was staying: cutting board, wine opener, tin foil, and oil. The kitchen is fantastic, but it's lacking some basics. Still, i was able to cook a lot, and I really appreciated being able to use the oven, fridge, microwave, etc. Just come prepared if you have kitchen items you rely on. Luckily, there is a Von's just .5 miles away from this apartment.
I went to the beach every morning and then again in the afternoon. There were quite a few sketchy characters lurking around (men alone/passed out or digging holes to pass out in, etc.) One guy was wandering around me for a while, getting too close and approached me asking if I found his other shoe. Huh? I didn't feel entirely safe at this end of the beach. I was surprised to see how much trash is along Alamitos Beach. There are trash cans everywhere! I'm guessing the water is dirty and most of it washes up. It's pretty gross at the end of the beach near this AirBnB, but if you travel down a bit, you can find cleaner spots. My recommendation is to try Rosie's Dog beach or go to the Belmont area. The separated walking/running and bike paths make it super easy to get from this AirBnB to anywhere along the beach. It's a great ride - super flat and super convenient!
