Spawn: 170, -155
Igloo: 528, -411
You start off looking at one of the two main villages and have a great chance to explore and get some good loot straight away. If you dig below the village center, you'll even come across some Lapis Lazuli. It's a cool little seed that will offer you a nice chance to get well equipped before venturing too far out.
The igloo is a bit further away, but it's right near some really great caves, so it's a fantastic home base. There's also a nice forest biome nearby, and even a couple of little beaches to visit.
