Sophie’s apartment was great for us (three 30-somethings traveling together). Apartment is spacious: three beds across two fully-separated bedrooms; a fully functional kitchen; a living space with dining room table and plenty of seating. Wonderful location. We walked all of central Paris and both sides of the Seine.
Great host: communicative, honest, and helpful. There was mild construction and scaffolding as of April 2018 and Sophie let us know and provided a fair discount. I would not let this deter you from staying at her place - it was not overly disruptive. Will be completed shortly.
The only really consideration/downside (if you are debating between hotel vs this Airbnb) is the bathroom, which high-end travelers may balk at. However it was perfectly acceptable for our needs.
You won’t find a better spot for the money in this part of Paris!
