I don't know exactly what happened with this place, but they used to be my favorite. Things seemed to slip a little with them after a) the Russian invasion of Ukraine happened and no more Russian visas to US, and b) they moved out of their old location which I used to like a lot. I think they always had Latinas mixed in with their Russian providers, and I would always ask who was working before going. But now they seem to mostly have Latinas, which is fine, but they used to have great Russian women. I don't know if they still do, I don't get out to Brooklyn enough.
They are very reliable, though. I always get a reply.
