Good hotel, but beware of the crowds
Stayed at the Sheraton for a week while we visited Lisbon.
Spacious rooms, all the amenities one requires, however the mattress was too soft for our liking. They did provide hard pillows on request.
The staff are polite and very helpful, and this came in handy with an issue with our booking. Despite having booked on a B&B rate, every morning the restaurant staff would tell us that breakfast was not included, which required a visit to the front desk to sort it out. We were hoping that this would be sorted after the first day, but unfortunately this carried on for 3 more days!
The spa is very nice, and so is the Panorama bar - make sure you get there in time for a sunset drink.
The food is good, even if the menu is limited, but the wine selection is good. We just asked the bar staff to recommend wine, and nothing was disappointing. A special thank you to the bar staff, who made us a special cocktail on our last night there :)
One disadvantage of staying there is that the hotel is popular for conventions, and was extremely crowded at times.
We would definitely stay there again.
