Look for clean and not in a neighborhood where you feel naked without an Uzi. Look for closeby cheap places to eat and public transpo. If you have a car, what about parking?
If it's a house without maid service, don't hot-bunk. Make sure you get your own bed.
Some of the best places are setups like long-stay hotels that have like 2 bedroom apartments with 2 beds in each room and a foldout couch. Maid service every day, gym membership, and maybe free breakfast, and free hotel van to the airport. If the hotel can manage it, you can get maybe 10 guys in the apartment with very little occasion when more than 2-4 are there at any one time. Often times the hotel you can make a deal with the hotel that anytime you get over 5 in the room, they'll give you an overflow room free. Expect to pay about $300 each for this kind of setup, but it's the most hassle free setup you can get.
