I have no idea if that claim is true, but what I did love about visiting Finland was the even the small apartment I rented had a sauna in it! It seems like it's a non-negotiable for even the smallest accommodations.

The cheaper apartments tend to not have private saunas built into the bathroom, but most apartment complexes at least have a shared sauna on the top floor. Residents can book a block of personal time in advance.

In most buildings the shared sauna is on the first floor (basement) and not top.

Also there can be blocks of time regularly scheduled, for example on weekends.
