I have never done a legion playtrough (*starts hiding for legion fan assassins :ninja:*)
So i was wandering what does its looks like?

Funny. I've only ever noticed the bed with the Lucky Shades. Never paid much attention to the interior decorating. :whistling:

You don't necessarily need to do a Legion "playthrough" to get the safe-house. The trick is to collect NCR dogtags. Lots and lots of NCR dogtags. Steal from every single NCR soldier you run across. Do the bunker thing for Caesar (upgrade or destroy, either one), and maybe do Finger of Suspicion. Get Liked status and you can get the key. Then you can betray them all at your convenience.

Bit rubbish really. I can't remember the upstairs well but it's like a single room of a derelict house, then you go into the basemant, it has three(?) beds with gear on and various empty storage things around.
The best item is without a doubt the Lucky Shades, some nice armour for Legion fans who may find it hard to acquire otherwise and some nice weaponry (chainsaw and displacer glove IIRC) but they're low repair when you get them which kinda svcks.

It's got one of the best locations imo as well, when I first went there I was like "ah, now it all makes sense..." Nothing exceptional, but explains Nipton, Searchlight, the ease of their raiding parties and it's not an obvious place for scavs to visit.

I have never done the quest and i killed Caesar and iam hated by CL.

its my favorite house. nice shelves for all your weapons, perfect amount of storage, campfire, and awesome location (i love going next door to the nuclear place and sniping all the ghouls.)
