The staff is very kind but they speak only russian and all information is in russian. Without your own guide, it's more difficult.
At the end of visit, you can see a small exhibition about the tragedy of kursk.
If you use subway, it's about a quarter by foot from the station.
This was a fascinating museum. We were able to use our guide to translate the submarine commander's information about the sub. Understanding how these men lived during the times these subs were used was really interesting.
