We travelled to Paris during Spring Break with my wife and teenagers.
Pros: Clean, two bedrooms (with two single beds for my kids to sleep separately in the 2nd bedroom), walking distance to Eiffel Tower and good access to the metro, which we used a fair amount.
Cons: The only real "con" is that even though it is within walking distance to the Eiffel Tower, it is a bit out of the way from Louvre, Notre Dame etc). In the evening after dinner we would take a taxi back and it was only 10-12 euro, so not hugely inconvenient, but if you want to be truly in the heart of the city it is just a bit out of the way. On the other hand, our apartment was in a quiet area so this is just a matter of preference.
The communication from Bertrand before the trip was great and we were very satisfied overall with our stay. For a family wanting to visit Paris this is a very good option.More
