Natalia's place was perfect for my four-day stay as a tourist. It's very centrally located, has all you need, the bed is comfortable, water pressure in the shower is good, and it's very quiet at night. It was very clean, Natalia was very responsive and the check-in process was easy. I would definitely stay here again!
A couple of (manageable) things to note:
* there is some construction going on in the neighborhood at the moment (like in much of Paris), and that noise started around 8 a.m. some days, so I had to close the windows at that point. But during the night, it was super quiet.
* as happens sometimes in older buildings, there's a faint unpleasant odor that comes out of the shower (and sometimes kitchen) drain. It's faint, but was noticeable to me. I put something to cover the shower drain when not using it, and it solved the problem during my stay.
Overall, I was very happy with Natalia's place and found it good value.
