Helsinki is, for some reason, full of massage parlours.

There’s a neighbourhood called Kallio that was formerly rather cheap but has become much more expensive and gentrified, and the massage parlours remain. I have no idea how they can afford their rent, as I’ve never seen anyone going into or coming out of one of those venues.

Obviously they provide “extra services”, but I don’t think that can be enough to sustain them. I suspect money laundering from drug sales etc.
