We stayed at the Clotilde's place for four nights. The apartment provided lots of space and was a great place to come back to after a long day walking the city (especially making a cup of tea on those cold, rainy days!). We enjoyed walking through the park to get pastries at a local boulangerie. It's an easy walk to the catacombs and there are two train lines close by.
There is very reliable wifi, but no TV (not that most people would miss it). The apartment does have steps and some shorter ceilings so it may not be perfect for those with accessibilty issues.
We really enjoyed our stay!!
