budget guest houses in Bukhara and Tashkent

Hello,
has anybody recent information about Karma Tapa's unofficial "guest house" in Tashkent? This was an old lady selling food on Darvoza avenue (south of Chorsu), who put you up in one of the living rooms of her family, in one of the soviet blocks nearby. They also had an unofficial very small restaurant on a terrace.

I've seen on this forum that Madina's guest house in Anwar street, Bukhara, is still working apparently. But I've also read something about guest houses checked by the authorities in the last months. I don't understand what problem might result from this for a tourist though. Madina, unlike Karma Tapa, and like Mobijon in Bukhara or Bahodir in Samarkand, would always register you and give you a docket. As far I know, there were guest houses who were perfectly known and authorized but were not allowed for tax reasons to have visible signs on the street. And a few years ago I didn't have problems at the airport when leaving the country with a few nights "missing": they didn't even bother to check the dockets.

It do happend that police checks the hostels and "close" it down saying their papers are not up to date or whatever. A couple of hours or the day after everything is back to normal. last year that happend to both Madinas place in Bukhara and at Bahodir in Samarkand while I was travelling in Uz.They did not check the registartion slips at the airport. But they did that at a checkpoint near termiz. They counted for every single day and obvious they were looking for a way to give me a fine. Generally they were checking your papers a lot more at the checkpoints than at custom.
