I am looking for accomodation in Key West with a pool and quite central for around £70 per night for three nights in September . Can anybody recommend anything please?

I think they take USDs in Key West.

Take a look at the Chelsea Hotel... perfect location and with the strength of the pound, you should be in that price range...

Is that roughly $140 a night, or a little less? The Best Western Hibiscus is on the quiet end of Duval Street and gets very favorable reviews. You might also check its sister property, the Southernmost Hotel.

September is hot and steamy, and also the height of hurricane season, so you could probably find lots of options.

We liked the Olivia by Duval- it's two properties that connect by the pool. It's an easy walk to the busy end of Duval, but still quiet.

The Rum Runner is farther down Duval. They have a good rum bar.
