This property is a great base camp for exploring the city. The apartment has everything you need for a comfortable stay in Paris.
I traveled with my wife and two children (2 & 5 yrs old). We enjoyed the central location and easy access to transportation.
The neighborhood is a little gritty. There is construction everywhere and it is located on a busy street so traffic and police sirens seemed to be a constant. No big deal to us but it could bother some. I think the price reflects this location because you would probably pay much more if it was located in a more polished neighborhood.
My only other comment is about the staircase to the second level. It is steep. almost like climbing a ladder. I was scarred my 2 yr old would topple the entire stay. If you have a wobbly kid beware.
Overall, it was great. We would stay here again on our next visit to Paris.
