Brand spanking new hotel, was there lot long ago as they were finishing it.

Usually stay at the Hilton Warsaw, never on points as always been able to get good rates and taxi is cheap to airport. They have airport train but time are rubbish, I was on 11am to LHR and got taxi as the train was either very early or a bit too tight to make connection. If you can get the new hotel, I would give it a try, right opposite check in, and if you get high room should be able to some of the airport
