Best way if you want to stay in Amsterdam is to take the train from Schiphol Airport. Every few minutes a train departs from platforms 1 or 2(which are next to eachother). Other posebility is the tram or bus to Amsterdam central station. Taxi's are a disaster especially in the city center. So it is a walk either way. Thankfully a lot of hotels are near a bus or tram stop. Another possebility is a B&B, often very good, and often a bit cheaper then a hotel(also they do their best a lot more to make it comfortable to you then hotels in my opinion so you come back quicker), through this site it is safe to book:
Bed and Breakfasts Amsterdam | Bed & Breakfast Netherlands, if you keep prefering a hotel in city center or just out, keep in mind there is a lot of walking with luggage. The best way to travel in Amsterdam is by walking or public transport(or take a bicycle when you putted your luggage away). Taxi's and cars are a disaster, especially in the center as people keep walking a lot through red light and why often taxi's can't get you to your destination. And as long as you stay with your luggage, there are barely any problems as long as you keep your eyes on it/stay put on it. If you don't, well, be prepared someone will call the police due to luggage left unattended. Also your camera bag, put it on your suitcase, or if you can sit, on your knees, also, put your wallet in it if you have it in your back pocket of your pants so you can keep an eye on it.
