Accommodation

There are many hotels around IAP at various prices. See for instance hotels near the IAP. Since there is a touristic rush in July (whether you are American, Japanese or Russian, you will certainly have the opportunity of meeting fellow countrymen in the streets of Paris!), we advise you to make your own (on-line) hotel reservations as soon as possible

If you're short on money, try the low cost housing near the IAP
