Our host Salim was extremely helpful from start to finish, offering to organise taxis for us, giving us plenty of helpful directions to local stations and popular shops.
We booked ourselves the Paris Visite metro pass. The best way to get around to all of Paris and experience the culture from a more local perspective.
Everywhere we went either spoke passable English or was very helpful with hand gestures. Very friendly people and the city overflows with historic culture.
If you are planning on spending time in Paris, take the time to consider AirBnB stays like Salim's. You will see a side of Paris never possible in the overcrowded tourist traps.
