Where to stay before an early morning departure?
Hotels near the airport
You won't find any hotels or guesthouses right next to the terminal.
The only private accommodation Chambre chez l'habitant avec famille within walking distance is about 500 metres from the terminal in the local area of Ikhourbane.
Hotels in Agadir
Significantly more convenient, however, is to stay directly at your destination and take a taxi to/from the airport, which you can easily arrange at the hotel reception.
we used the mentioned accommodation for the night before our departure - I recommend to read the reviews on booking.com from the "lowest" rating - they correspond to reality.. the description does not mention that it is a shared bathroom with all the other residents of the house... the windows don't seal out the street noise at all (and I had earplugs too). The price per night was 500 more than the price of a taxi in Agadir.. for me it's better to stay in Agadir and get some sleep, plus there won't be much traffic on the road early in the morning and the ride to the airport will be no problem...
