Understanding the luxury of the hotel rooms and condos at Raffles Boston Hotel & Residences will simply be a matter of glancing at price tags.

When it debuts this summer, the $400 million-plus Raffles (40 Trinity Place) will have the most expensive hotel rooms in Boston. Hotel developers Gary Saunders and Jordan Warshaw weren’t keen to talk numbers, but after a fair amount of prodding, they offered up a few details.

“Our rates will be the highest in the city because we believe we’ll have the most unique and special product in the city,” Saunders said. Hotel rates vary wildly by season, but generally, ultra-luxury rooms in Boston run in the mid- to high-hundreds to just over $1,000 per night. “When you see them, I think you’ll understand why,” added Warshaw. “That’s why we expect these to be at the upper end of what’s being charged in Boston.”
