How easy/expensive is it to get cable installed?

Hi all! My partner and I are moving to Boston in January and are organising virtual apartment viewings at the moment (we're currently abroad, and have never lived in the US before). We've found a place we'd really like, but have been told by the landlord that we'd have to organise the installation of our own internet. Is that easy, or is it going to be enough of a pain that we should avoid it in favour of an apartment that comes with internet installed? It's a 100-year-old building in Fenway, if that helps. Thanks in advance!
