Can you solve Einstein's logic problem

There are five houses lined up next to each other along a street. Each house is a different color, and each homeowner is of a different nationality, drinks a different beverage, smokes a different brand of cigar, and owns a different pet.

If these variables can never repeat from house to house, which homeowner has a pet fish? You should be able to figure out the answer based on these 15 clues:

The Englishman lives in the house with red walls.
The Swede keeps dogs.
The Dane drinks tea.
The house with green walls is just to the left of the house with white walls.
The owner of the house with green walls drinks coffee.
The man who smokes Pall Mall keeps birds.
The owner of the house with yellow walls smokes Dunhills.
The man in the center house drinks milk.
The Norwegian lives in the first house.
The Blend smoker has a neighbor who keeps cats.
The man who smokes Blue Masters drinks beer.
The man who keeps horses lives next to the Dunhill smoker.
The German smokes Prince.
The Norwegian lives next to the house with blue walls.
The Blend smoker has a neighbor who drinks water.

From there it's a matter of elimination after starting with what you know is true and what you know is not true.

I made 5 separate columns, one column for each house, listed like below and began with the easiest clue that the Norwegian lived in the 1st house. From that, I lined out what wasn't true and circled what was true until, by the process of elimination, I arrived at the answer.

1st House

Norwegian
Swede
Dane
German
English

Yellow
Blue
Red
Green
White

Blend
Prince
Blue Master
Pall Mall
Dunhill

Horses
Dog
Cats
Bird
Fish

Water
Tea
Beer
Milk
Coffee

Does that mean "the first house on the left"? Or "the first house on the right"?

FWIW, assuming it means "the first house on the left" gives an answer (same as some people above).
