Continue to go straight to the pharmacy. Opposite the pharmacy cross the street and turn right. Went to Reaching the corner, turn left and go straight two streets to arrive at to the museum. I have not lost?

Your words are correct, but you need now to start writing in the way the English speaker does:

I need to leave the hotel and turn right to walk to the end of the street.  There I turn right, and then left again at the first corner.   I continue to go straight to the pharmacy.   When I reach the pharmacy, I turn right.   At the next corner, I turn left and go straight to the museum.   I did not get lost, did I?

You will find that it gets easier over time.   :-)

Good job! Perhaps:
 
I need to leave the hotel, turn right and walk to the end of the street. Then cross the street, turn right and then take the next left. Continue to the pharmacy, turn right when there, and then take the next road on the left. Continue to walk straight ahead past the junction and the museum will be on the right.
