I'm a french person, 29 years old, enjoying travelling !
Martial was a perfect guest ever, he was a great connoisseur of the city, with a lot of friends here, and he didn't need any kind of advice. He is a very polite and educated person and you can trust in him.
He always answered very quickly all the messages and had a very good level of comunication through the entire trip.
I'll be glad to have him as güest whenever he wants to come again.
