I got all the addresses from a leaflet that was available for free at the entrance of Velvet, but SirMarj couldn't see it in his recent visit so that may not be available any more, maybe Sofia City Guide is the best option now, or some other local magazine or paper with ads in English.
Once I got the adresses and phone numbers I phoned to ask for opening times, and then got a taxi to take me to the different addresses - that was straightforward.
