Thomas, things you might ask if they offer are:
Mastermind groups: A group of 4-5 people, over several weeks, take turns putting their group attention on each member's idea/business. So you get an hour's work of brainstorming/feedback, but showing up for 4-5 weeks in a row.
Accountability groups/Standup: Similar but different. Basically say what you're doing to do, then people in the group hold you to it. Daily meeting to get great way to get feedback on your realism and productivity.
Demo Days: Similar to Accountability groups, but ever 2-3 weeks you give a demo of what you're working on.
What is the hacker house offering?
If it's just being around "talented people", their best talent may be selling, instead of hacking.
