We had a wonderful stay at this place and agree with the previous positive comments. The best quality of this place is the location since it’s close to attractions in the 1st, the Metro and Île de la Cite (Notre Dame). It’s very easy to get to from CDG via RER (B) train then Metro.
As noted by other reviewers, be prepared to walk up some stairs. After a while you get used to it.
The place itself is quaint and what you would expect from a Parisian style apartment but renovated. It has most of the amenities needed.
There are only a few minor things to get used to: there’s only one toilet, the showers are in the bedrooms and the upper floor gets a bit warm.
Isabelle, the host, was very accommodating when we asked for a slightly early check-in and was quick to address our request to get the AC running due to unseasonal warm weather during our stay.
Overall we would recommend this place.
