This seed is great for a start. You will spawn near the village and the mansion. The settlement is located at coordinates -204 ~ 164. The mansion is located even closer to the spawn point, at 8 ~ 8. On the first floor, you will see a very unusual and strange generation: a big Nether portal inside the mansion.
