The size of the flowers and their shape suggest portland as a class. Leaves close to the flowers is also suggestive, as is their dark color and smooth texture. The most commonly grown reddish rose in that class is Rose de Rescht.

Three problems with that guess are that:
1) it's supposed to have strong fragrance,
2) it has a reputation of being well branched and shrubby,
3) the flowers don't look quite exactly the same.
But after looking at all the photos of red portlands at HelpMeFind, I can't find one in this color that is closer to the shape. And, in fact, that beautiful dark green foliage that RdeR has, seems to belong to your rose and be kind of rare in old roses.
From what I can see I couldn't rule out the gallica Charles de Mills

Or Louise Phillip

Or even Kean (aka Shakespeare)

Maybe it could be a gallica. Gallicas tend to make long canes as your rose does; but the leaves of many Gallicas have more texture and tend to be brighter, lighter, or yellower. I'll list some less likely ones just for the fun of looking at them.

I've not researched hybrid perpetuals on the assumption that its small flowers preclude that. Same for English Roses.
If it repeats, it's definitely not a gallica.
If it doesn't repeat it's definitely not Rose de Rescht. Nor is it a hybrid perpetual or an english rose.
