I grew up in a city of mostly rowhomes and I love them. Plan on buying one one day.
You still get walk-ability, sense of community and good population density (not as good as a high-rise but still good), but also more privacy, and the space is more conducive to raising a family than an apartment. Also they’re cute as fuck and people can paint them different colors and have cool little gardens on their porches and stuff.
Montréal has a fair amount of these and they’re pretty cool. Also variations of this ofc, like sometimes it’s not fully connected, but in groupings of four units with little passageways between the buildings, or they might have little yards or be 3 units tall, really depends on the area.
I helped a buddy of mine move to montreal into a rowhouse that looked just like this. First winter there, he ended up slipping down his second story staircase. Funniest phone call i’ve gotten in a long time.
