Great location, great style and comfortable. The loft is cozy and you get a lot of space to live which is hard to find in downtown Paris at this price. The bathroom is a bit open so make sure you're comfortable with who you're staying with! Also, make sure you're ok with narrow stairs as they're a bit difficult to use to get up to the loft.
Overall, Hiroko was a great host that didn't have any unreasonable demands. She was extremely flexible on the check-in time and provided a lot of information on how to get there.
Highly recommend this space! 10 minute walk to Notre-Dame and much more!
