Beautiful historic hotel in a great location
We stayed at the US Grant for one night in San Diego and it was a great stay! The staff were all very helpful and accommodating and the location couldn't be more convenient. It's a 10-15 minute drive from beautiful Coronado and walking distance to a lot of shops at the mall across the way and all of the restaurants in the gaslamp district. It's also within walking distance of the convention center.
While the hotel lobby itself is newly renovated, I felt it did lack a bit of character and still looked dated. I was really surprised when I went into our suite though, which was really beautifully decorated, but still retained the historic character of the building. Very stylish and understated. 
All in all we were only there one night, so I can't comment on the breakfast or the other facilities, but we were happy with our stay. But one thing I really have to complain about though - the $35.00 parking! We were thankfully able to find an overnight lot on fourth, for $15.
