Translation of charlatan in Spanish

Our day came to an end and Samu brought us back to the hotel. We agreed to take a ride with him one more time and that was on the way to the airport. We took his cellphone number just in case.
However, his English was excellent and we soon found out that he was an English teacher before the war. We agreed on a price for showing us the entire area during the next 2 days. We took a nap and he picked us up later.
In Bariloche it took us around 3 hours to find a nice hotel. The prices varied a lot and there were no bargains. We settled for the Hotel Tirol, owned by an Austrian lady. It was a cute place with a lake view.
