Here is the Pears of NY description:
Urbaniste is another variety desirable for home use because of its highly-flavored fruits so sweet, rich, perfumed, and luscious as to be a natural sweetmeat. The fruits are of but medium size and not particularly handsome, but the taste excels the looks. The flesh is as tender, sweet, juicy, and as delicately perfumed as that of Seckel or White Doyenne, but with a distinct flavor and scent which give the fruits the added charm of individuality. The crop ripens in October, in a season when there are many other pears, but the fruits stand comparison with those of any other variety and are welcome additions to the fruit-basket. The trees have several defects, chief of which is tardiness in coming in bearing, to remedy which grafting on the quince is recommended. They are also susceptible to blight, and are not as hardy as might be wished. Of all pears, the tree of this variety is one of the handsomest clean and tidy, slender and graceful, yet robust and productive. Fruit and tree make this a valuable variety for home plantings.
Urbaniste originated as a wilding in the gardens of the religious order of Urbanistes, Mechlin, Belgium. After the suppression of this order in 1783, their gardens remained uncultivated for some time and produced new seedlings of considerable merit. The beauty of one of these attracted the attention of Count de Coloma, a well-known pomologist, who acquired this property in 1786, and in due course propagated and disseminated the variety under the name Urbaniste. Early in the nineteenth century, Count de Coloma sent specimens of the pear to the London Horticultural Society, which organization afterwards distributed it in England about 1823. Thomas Andrew Knight sent cions to John Lowell, Roxbury, Massachusetts, through whom it became disseminated in the United States. The American Pomological Society added Urbaniste to its fruit-catalog list in 1852.

It takes awhile to get into good production, I would say that is the main downside … it is similar to Magness in that regard. It is also on the small side, bigger than Dana Hovey but smaller than the standard pear size.
