Nice, cozy flat with views of Notre Dame. If you like to walk, things aren’t too far away. Notre Dame, le Marais, Le louvre and Luxembourg are all minutes away. Mon Marte and Eiffel Tower are walkable under an hour but even quicker by train.
Lots of good food around too. Literally right behind the flat there is a restaurant called Au Bognat that is one of the best places I’ve ever eaten in Paris.
Only thing to really be aware of is that this is on the 5th floor, with a spiral stair going up. It’s a hike up every time but you get used to it.
