Thanks Michel
So some small notes would be useful, too?

There is an ATM in the Dedeman Hotel in Tashkent (opposite to City Palace on the LP map). It accepts Visa and gives money in Som. But max amount is 40000. I didn't try to get US$ from it though.
In my experience many hotels and guesthouses also change money at black market rates. It seems harder to get good rates for Euros. Therefore I changed US$ only.
