I had a wonderful experience with Spoedteststraat to get my PCR test and supporting documents for a trip to Hong Kong. Their customer service is extremely helpful and responds fast. The staff at the Schiphol location is knowledgeable and very friendly. I got my test results in less than 30 minutes (I booked the emergency test). They even helped me print multiple copies of the documents I needed. The tests were approved for travel to Hong Kong, which currently has one of the strictest entry requirements in the world (make sure you also print the consulate letter and RIVM's list of approved covid-19 laboratories). Overall, I'd highly recommend them!
