I'm Julia I live in Paris with my boyfriend Nick, our appartment is really nice and big with lots of light, cosy too (5th floor). Our room is really spacious and our bed's really comfy. Good location, central, 20 mins walk along the river from Notre Dame, really well connected - two metro lines (5&6) at either end of the road. We also have a balcony that gives out onto the little park that's in front of the building, which has a lift.
Hope you have a nice time in Paris! :)
Walking is always best in Paris, but the metro system is really good!
Round the corner are Campo Formio (line 5) and Nationale (line 6).
