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.
