Sorry for late response. Three good Meals (breakfast, Lunch & dinner) won’t cost you more than 120 Grivna=$20/day. However, if you go to pubs or somewhere every eve then add $10 to it. Weekends might be costlier... If you go to a nightclub. ;-)
Personally I feel comfortable with a budget $50/day. It’s as if you spend less one day, then few dollars more on the next day. Moreover it’s summer there... too many booz... too many girls... and mind you, above figures are for only one person. In case you are meeting with a Ukrainian lady… then I suggest you hiring an Accountant. :D LOL
Take care and have a nice trip.
