The guide was on time and took care of the entrance fee. He was very knowledgeable and the tour was long enough to get a feel of the sewer system in Paris.

Tour guide was exceptionally knowledgeable and cordial. Wouldn't reccomend the tour in the summer, as the odor was bad enough in October. Fascinating all the same. Do it.

Very interesting and the young French guide was charming. The only thing was, we could have used a little less talk and more time looking at the exhibits, especially those with text, And my friend wanted to buy a stuffed rat for her son, but the boutique was closed for lunch ! We especially appreciated your call explaining where we SHOULD have met our guide I forgot to re-read the sheet. What a great engineering feat.

3 star rating: Worth doing June 2016

Guide was smart and cute but spoke so fast and accented it was hard to keep up with in the sewer. All in all, however worthwhile.

Something different to do, quite enjoyed this tour. It wasn't hard, and we learnt a few things as well as seeing something quite different. More technical information rather than stories. I thought we'd have ride on the odd contraption in the picture, but no.... still good to do for a different perspective of Paris, recommended.
