Jérôme's place is great : very clean and well-equipped, in the middle of everything and, cherry on top of the cake, is extremely quiet.
From Jérôme's place, you'll be able to walk around the centre of Paris and if you feel like pushing farther, the subway (Line 1) and buses are all around.
One minor suggestion would be to replace the A/C. Would be much appreciated and useful during heat waves.
Jérôme was very pleasant and went out of his way to make us feel welcome. I would definitely recommend him as a host. Thanks a lot for a great stay !
