they are the ones that are 2.5 stars, sometimes 3, but everything higher is pretty much "secure." Every time, when I was trying to get a higher than a 3-star hotel, it would give me the one with the paid parking, not free internet, and secure access.  If you shop for the hotels online and you can choose which one you like, you can call them and ask. I think it's the best way.

That's what I did when I was there, anyway. It was much more discreet than any hotel I've stayed in. Just be sure to avoid the high-rise type places (almost all have a doorman and you definitely don't want that).  

Feel free to PM me if you'd like some more specifics.
