The apartment is nice and true to the photographs, although a little small (like all parisian apartments). The reviews about the area being vibrant are spot on - this is real Paris, with hip bars and restaurants down to St Martins and some slightly less favourable characters further away from the canal but nothing threatening!
The kitchen and bedrooms were clean and well sized, the bathroom is lovely. The only issue we had was that in the small bedroom the blind didn't really keep out the light and, combined with a vibrant neighbourhood on a Friday/Saturday night with thin Parisian walls the much lighter sleeper of us struggled to sleep.
Overall we enjoyed our stay, the kitchen was well stocked, the apartment nice and the area trendy - but probably not suitable for very sensitive sleepers
