Translation of impostor in Spanish

We bought some sandals which cost us two dollars each pair. Then we visited the surroundings of the market where many store sold paintings, sculptures and books, some very beautiful ones.
I wish you a good trip, when you come to Germany in June! How do you long stay in Berlin? Please help me with my English, in return I will help you with your German. Wish you a nice day!
We asked for the price and were surprised to hear it: A hundred dollars a night. We were actually happy to hear the high price because we knew that if we would not find anything else there was still a good place to stay in.
