Basically a lovely property, well maintained, in a very nice neighborhood, and just a couple of blocks from Duval, the ‘main drag.’ For a Select Registry property the manager needs to be more hospitable and attentive to guests. The happy hour, wine and cheese, in the afternoon needs a considerable upgrade and the breakfasts were quite ordinary.
