A friend of mine swears by the Portland Square, informing me repeatedly that James Cagney used to stay there. I checked out the Web site and walked past it, and it looks fine, pretty basic. If that's what you want, give it a shot.

I've found that www.quikbook.com sometimes has very good rates for high-quality properties (I've seen $150 and lower). It all depends on time of year, no matter who you book with.

Then there is Priceline. Take a look around Sheryl's Web site for insight and experiences.
