Have booked the apartment and the transport from Odessa airport to Nikolaev and back. In short, only I can say that the service was PERFECT!
The apartment looks same as on the photographs, published on this site; it's maybe small, but it is cozy. All installed equipment works fine, but don't expect that you'll have many programs on sat-TV. I asked for Internet connection and laptop for rent and this part was perfect too. The internet connection is fast, but I recommend to bring your own laptop as some programs have Russian menus, which are difficult to change to English. However, I changed Skype program to English.
One advice: order VIP service on airport when departing Odessa; next time I'll for sure order it. Dmitry, thank you so much, I enjoyed to stay in Nikolaev. In addition, I'll ask you for help me in everything else as I see that you're well organized.
I am currently in Nikolaev and am not one bit sorry that i visited your City, the people are nice and friendly! Regarding the car you sent to pick me up, was excellent and sowas the driver, nice and helpful so much so that every time i opened my mouth he would phone and give me the telephone and he will just say translator :) so i figured i keep my mouth shut because he was going to make a lot of expenses calling :) he was so nice and kind! I will be pleased to use any of your services in the future!
