I booked NX2.
I want to start by saying the following about the bad reviews I read: If you paid $25 a night to stay anywhere, you didn't pay enough to complain. :)
I work a lot so the only reason I booked it was because it was close to work. I wasn't planning on hanging out all day watching TV or having people over. This booking is a safe place to crash, get a hot shower and reset. That's all I needed it for so it worked great for me.
There is plenty of parking on the street and it's like less than 5 minutes away from 680. There are a bunch of other rooms in the house but everyone really kept to themselves. The only difficult part is the shower hustle in the morning: If you can find time at night to take a shower before bed DO IT!!!! Everyone trying to get in the bathroom in the morning so it gets hectic. Oh and bring an extra roll of tp: There is an emergency bathroom with a toilet but it's on a tank that prevents you from putting toilet paper in the toilet directly. You'll need to bring some in there with you, there is a little trash can next to the toilet use.
The shower temperature is GREAT! I never had a problem getting a hot shower. I didn't use the kitchen but there is one, and the neighborhood is really quiet.
I would stay here again. I might check out one of the other rooms though because I toss in my sleep: The bed was a lil small but I managed ok. :)
