Terrific location. Small but well-appointed ground floor apartment overlooking The Seine on the charming and tres chic Isle Saint Louis. Overall I enjoyed the peace and quiet one can find here by simple crossing one of the bridges over from one of the bustling adjacent neighborhoods. If you want to be in the heart of Paris where walking anywhere is a possibility, I would say this is a great option for 1 or 2 persons.
On the slight downside there was a lot of noise happening in the apartment above me, construction of some nature. This occurred sporadically for several days. When I communicated this to Luckey they mentioned 'they didn't know anything about it and would look into it' or something like that. They didn't follow up with 'yes we notified them' or 'we have made contact' etc. BUT with that said after a couple of days the noise dissipated so all is well that ends well I suppose.
My only other negative is that, as this is a compact apartment in the heart of Paris, it's not surprising that the bathroom is small. However, with that said, it's tiny. Of more importance, the lighting absolutely sucks. So, if you're on holiday and want to get a glimpse of yourself before leaving the house, this mirror / lighting may not put you in the best of moods. It's hideous. An update or at least updated lighting would change this dramatically (for the better). Something for the hosts to consider I suppose.
