The location of this apartment was second to none. You can be on the Seine in 5 minutes, Notre Damme in 10 and the Louvre in 15! Rue St Denis has so much going on and the bars etc are excellent with plenty offering happy hours.
The flat itself is small and i would recommend this for an individual traveller. We travelled as a couple and it was very tight for us both, but there are plenty of amenities in the flat.
