Great little place in a great neighborhood. Within a few minute walk of the metro and just a block of the Rue des Martyrs. Has everything you need and nothing you don’t. Caroline is very communicative and helpful and even provides morning espresso and coffee. Bathroom is ample and airy.
I would, however, be remiss if I failed to mention that the bed is small. You will essentially be sleeping in a twin child’s bed with an identical bed on top ( I assume this bed will be available if you have another guest in your reservation since it was locked for me). As such, I would not recommend this place if you plan to engage in romantic activities with your partner in the most romantic city in the world. Great for single travelers and/or friends without benefits.
I also offer a helpful tip in case this trips you up like it did me. When Caroline sends you the access instructions she talks about a screen and how to call her from the door. She also sends you the address and an alphanumeric code. Be aware that this alphanumeric code is not a postal code (as I thought) but a code which must be entered at the blue external door which gives you access to the building from the street (before you access a second door with the screen from which you call Caroline).
