Here are five questions at the top of your list:
What's my budget? Currently, hotel prices are published on their website. So there's no reason why you can't research how much it took to get a room somewhere. You need to know what you can afford so you don't overspend.
What comforts mean the most to me? Some people only need the master bed, shower and telephone to wake up. Others need more, but "need" is the right word. Some people like the benefits that can increase your price.
You can also choose hotel near Santa Monica pier.
Is closeness a problem? If your hotel is far from the airport you are entering, it may take a while to get to your destination. The more you have to move back and forth, the more time you will spend having fun.
How will I travel when I am there? It is easy to walk in some very nice cities. But for others, you need to consider using public transportation or renting a car. Your hotel deal might be a good one, but isn't it far enough away to make it difficult to travel?
Do I like the offer (last minute or not)? Some people book rooms based on the price they see. They take out their credit cards, go through the ordering and booming process, and go on trips.
Others want a good deal and are willing to negotiate a price or even use a travel app on their phone to get last-minute hotel deals. Where you fall on the spectrum varies, but it's good to think about.
