The flat is very cute and small, great for a 2-3 day trip! The location is amazing which makes it really easy to get to everything in Paris! The flat has a small kitchen and kitchen utensils that were very useful for when we were way too tired to go out for dinner.
The only thing that could be added as a negative is how there is pretty much no sound insulation and therefore we could hear everything that the neighbours were doing and lots of pipe sounds during the night - so bring earplugs!
