I can’t comment on these twinhomes specifically, but I owned a twinhome in Pennsylvania and loved it.
But then again – it was everything you said you didn’t want… It was old (circa 1905). It had laundry in the basement, detached garage, small- almost non existant – closets.
But it had 10 foot ceilings, beautiful casework around the doors and windows, and charm out the whazooo.
I could occasionally hear my neighbors through the walls. But I got along fine with them and it was never an issue. I had a nice garden and yard. I had no HOAs and the covenenant specified that I couldn’t run a tannery or have a manure pit in the backyard. (Covenant dated to when the area was subdivided in 1898.)
