Maria; The most professional tours company manager I have ever dealt with offered us :
1- Very reasonable price.
2- Very fast response.
3- Premium buses.
4- Tatayna the tours guide in Moscow: a super tours guide; with great attention to all details.
5- Maria; a super guide in St. Petersburg. Again with great attention to all details.
6- we saw all major attractions; attended a very nice folklore show, went to great restaurants and still had a great half day to walk around.
7- Priora tours are not cheap. They do not charge you for every extra service; its like their target is to make you happy rather than anything else.
I can definitely see myself arranging more trips to Russia. Take my advice. Call these people; they are really good.
