Not sure about the Edinburgh ones (I suspect not though).

I'm pretty sure that Glasgow doesn't. They do have a laundry/dry cleaning service but it isn't cheap. The service is definitely available though as the laundry company was dropping a guests stuff off when I last checked in.

I stayed at Indigo Glasgow on Friday, it's still a nice hotel but I feel it's starting to lose a bit of shine. There doesn't feel as if there is the same attention to detail that there used to be. Still a very nice hotel though and the rooms are still in a very good condition.
