Good, central flat, a choice of Metro stations in easy walking distance to get around Paris.
Plenty of places to eat in nearby Rue Montorgueil, and Les Halles.
The RER B from CDG airport to Les Halles is about 10Euros and the best way to get into Paris. You can then walk to the apartment or get the Metro to Reaumur Sebastopol
which is on line 3 and 4.
Getting into the apartment is a bit of a faff, there are 3 locked doors with key pads, you punch in a different number for each one.
While we were there the drains smelt terribly, not so nice in the bedroom with the open shower and basin in the room.
There is a bar on the corner of the street which was noisy on the Friday and Saturday night, resulting in sleep disruption for those sleeping in the rooms at the front.
