having trouble finding location in Brevik

Good afternoon! I show an ancestor, Ole Petter Johnson, and family living at 31 Øen Gate in Brevik 1885 Brevik Telemark census and at 294 Øe Roden, also in Brevik in 1865 1865 Brevik census but cannot seem to locate these addresses on a map. My grandmother went to Brevik in 1963 and took a picture of what our family thinks is the house but so far have been unable to confirm it. Thanks in advance to anyone who can provide some assistance!
