In the capital of art and fashion there are many free or almost free things to do and see. If you are rich enough to buy a ticket here, you can find ways to make it happen. The city has an atmosphere of adventure and everyone feels it once they are in Paris.
Love is in the air even in the middle of winter which is really mild in this part of the world. It rains but not terribly so. Umbrella and waterproof shoes might come in handy.
Walking along the streets you can hear all kind of languages. Great variety of food is offered at every corner, quality is quite high and prices are not bad if you are willing to wander off the beaten track. Supermarkets are awesome, Airbnb is super helpful, walking most places is totally doable if you are centrally located.
All in all, this city is worth a visit. The only concern is there are too many tourists all year round. Great experience is guaranteed if you read up a bit before you go. People are really nice and helpful, try to speak a bit of French and most doors will be open for you. Dream big!
