Our stay at Gautier’s place was good. Gautier had advised us that there were building works before we came, but we still decided to book. The building noise is not a problem if you are getting up early to explore Paris, the noise started at about 8am, so if you are planning on getting out early it is ok. Gautier was very quick to respond to any questions or queries.
There are metros and buses within walking distance which makes it easy to get around Paris.
My only small advice for staying at the apartment would to be to bring some slippers for your feet as the floor is very hard.
