Here in Europe and I guess specifically in Latvia most have washers or washer+dryer in 1 combo in almost every home or even individual apartment. My washer/dryer is in bathroom but I have seen people having them also in the kitchen. Depends how spacious said living spaces are. Newer homes or bigger homes have dedicated laundry rooms. 

Recently in one of the bigger shops here they opened a laundromat and whenever I go to the shop I hardly see it used. Maybe students use them if their dorms don't have washers/dryers or people who have run into trouble with their machines use them. Maybe it is hardly used due to the unreasonably high prices. I think it was around 7 euros per 9 kilo wash. 

I found American washers and dryers are so different from what we have here. Like, dryers for one work on completely different principles than what I encountered in States.
