Took Pakhamov from Moscow to St Petersburg in May. Standard cabins are very small. We learned now to compare cabin sizes with other cruise lines. We had a problem with the toilet in room, very bad odor and after trying several times and for several days to have the problem fixed they (hotel manager) moved us to another room. Tour director did not seem to care and neither did housekeeping except to "spray". My husband was very sick on the plane home and for three days after and had to see the doctor. I think it had something to do with the toilet system and/or water. They said drinking water ok at restaurant and from a water system to fill your bottles. I think not. Be safe and only drink bottled water!. Staff were wonderful and food was not as good as we had on other river cruise. It was once only trip on Viking for us and I will use another river cruise company next time.
