Paris is one of the most visited city in the world. So it is not easy to find available accommodations for tourists. Hotels in Paris are usually very expensive, but you can always try to rent a fully furnished apartment that would accommodate several people, in order to split the lodging costs.
The site 2 be in Paris is specialised in “appartement de vacances à Paris” ( holiday apartments in Paris ), it is very well organised, and you’ll be able to get your croissants in most bakeries down the street of any of the apartments that they’re listing !
