Place is located 20 steps from the Odeon station and is perfectly located if you are looking to explore Saint Germain. I was there with 4 adults and 2 children and this location was more than comfortable for all of us.
Check in was very easy.
We were a little worried about the 1 toilet in the location, but having 2 separate bathrooms (without toilet) it turned out to be ideal. (No kids wanting to use the toilet when taking a shower.)
Apartment is beautiful and well furnished. It's shockingly large for the location, and location, location, location. It could not have been a better way to expose my children to their first overseas trip. They didn't want to leave. Thank you MI, this place is amazing and we know where we will be trying to rent on our next trip to Paris.
