I traveled to New York and booked a hotel room on Agota. It was about $100 cheaper per night than any other travel site, and when I called the hotel in New York, it was also over $100 cheaper. On top of that Agota let me cancel my reservation and get my money back if I needed to change plans. I don't know Agota's business model or how their prices are lower than competitive travel sites, and I didn't need their customer service because my hotel turned out just fine, but for me it was a 5 star experience.
