The exchange rate was a little more unprofitable than in other exchangers where I was
One of the advantages is a sufficient convenient location on the Marina
A small exchanger without a commission, they also change rubles, but at a very unfavorable rate, you know why, so it's better to have dollars / euros. It can also be exchanged for other currencies (pounds, francs, etc.) for the collection.
The exchange rate is 3.64 per dollar at the official 3.65, everything is normal, exchange without commission for old dollars (although at the airport they convince you otherwise)
