In Paris, you’ll find accommodation for every type of budget. If you are one of those that comes in a plan mochiler/economic with the purpose of enjoy and visit the city, to live the parisian life I recommend you choose a budget stay, Airbnb is the option of +41, you can also find Hostels beautiful, economic, and breakfast included. Now if you come a little more baggy of money you can find hotels lindos, check out the options on TripAdvisor.
Well… that both the host and the tenant has a profile where “you need to stop reflected very well who it is, but the best thing is that both the host as a tenant have to leave a comment of another during your stay. This means that the profile can never be uncertain because sooner or later you will end up knowing. (whenever I travel, I use Airbnb,” are you going to be able to sleep at night and knowing that I paid a fair price)
As in all large cities, in Paris there are areas that are “dangerous” and others, not so much. I recommend that you choose the place of your stay depending on the proximity to a metro station, so you don’t have mobility problems. Tip, in the first perimeter of the outskirts of the city (banlieu) you can find nice places, good price and about 20/30 min. Paris. Down here I leave you a video to explain everything.
