Excellent experience, particularly with the concierge team, who were more than helpful in planning a surprise for a birthday we were celebrating, and who couldn't have been more helpful with maps, restaurant recommendations, etc.
The US Grant lives up to its name as a member of The Luxury Collection. The rooms are spacious and comfortable, the foyer is elegant and welcoming, and the service exceptional. I would definitely stay here again.
Hotel is located downtown so the only negative I could give was the sirens in the middle of the night. The staff is top notch except for a rather surly front desk clerk on check in. I wouldn't recommend for families but otherwise it is locate near the center of everything San Diego.
