There is a traffic light infront of Sofitel Ponte 16, cross the street to the opposite side then turn to your left, walk straight towards 'NamHeng Restaurant 南興牛雜‘ then turn inside the small road, you will see 'Caravel Hotel' it is a new boutique hotel (can't see from the main road). Once you found Caravel Hotel (either go inside ask the counter) or walk straight behind the hotel you will see Nam Ping coffee shop. It is right exactly one street behind the Caravel hotel. When you type in google map, you will see it. hope it helps.
