Here's some signs you may or may not be able to read.
We went to Moscow and Saint Petersburg last fall and we went Independently but we are very experienced travelers too. In the major cities, there's usually someone who speaks at least some English. We didn't venture out to other towns, but I understand the further away from the cities, the less English is spoken. In Moscow, some of the signage was also in English, but that was limited.
Russia is quite expensive. With respect to transportation, I'd never try driving in Russia since you don't know the language and thus the street signs. They have a very good (and rather pretty) metro system that we used regularly. It's best to look at a map before boarding and decide where you get off and count the stops and do the same on return since they move quickly and again it may be only in Russian. Many of the hotelshave a limo service that will pick you up or take you to the airport but again they are quite expensive. We did invest in that service though as we had no idea how to get to our destination and we wanted to get some rest. When we saw the traffic problems, we were glad we made that decision, too.
I look at the figure you were quoted of $200 Euros per day and I question where they will be making your hotel reservations and where you will have dinner. As I think back on it, our hotel and food was probably at least that but we were very careful to book our hotel near the sites we wanted to visit. We have learned that if you book far out you can spend much of your time in transit especially if you are 'language challenged'. I also took great care to go to different sites to see what others who had stayed there said about hotel safety, cleanliness, location, etc.
We enjoy traveling and the challenge of the various languages. That's part of the fun of vacation.
