The hotel is wonderful!!!

I can't answer about the lounge, since I didn't see it, but my experience was very positive.

I arrived about 10 PM coming in from Cape Verde, and had to depart on a flight to Frankfurt that left LIS about 0700. I asked at the desk when I should plan to get up to make that flight. They explained that the airport is only 10 minutes away, cabs are plentiful, and check-in easy at that hour, so departing from the hotel 90 minutes before the flight was more than sufficient.

I noted that that meant getting up about 0430 to dress and pack, and mused that I'd have to miss breakfast since the restaurant wasn't open at that hour. "Oh," said the lady at the front desk, "Would you like us to have room service deliver breakfast at 5 AM? No charge."

Wow! All that and the Platinum amenity (I chose the red wine), too. What a great hotel!

(And yes, I caught the plane with plenty of time to spare.)
