Hi Maria, really happy you liked our other article about Paris in winter. We think visiting the French capital in the winter is a great idea as it really looks stunning with its light decorations. There are fewer tourists and the prices are cheaper. But make sure you dress well. I must mention that during Valentine's Day Paris is a prefered city so if you decide to visit in February take that into consideration.
We recommend aiming for the 7th or 8th district during winter. It looks great and you can find hotels with views of the rooftops which sometimes get covered in snow. Really magical place.
