At night, the ruble exchange rate to the local manat is not very profitable, I do not recommend it. During the day, it's normal. One of the few places where you can exchange cash rubles (also local VTB). The exchange rate of buying back rubles is better here than in VTB (during the day!).
Everything is clear! it works at night, on holidays, on weekends, the rate is the same as in any bank, without commission and without interest.
I changed $ -1.69 manat, the exchange rate was 1.70.
