I stayed here for a week and had nothing but great vibes and excellent customer service from all of the staff throughout the property!
The only non-positive thing I have to say is this property does not have an iron or ironing board in each room, but that is normal when traveling throughout Europe. There is an iron you can share, but I was never able to get it. Luckily, there are multiple stores within walking distance that sell irons for as low as 15 Euros, so I just bought one.
Security was posted at each entrance, including the parking garage, made me feel safe. The property was very clean and well maintained.
There is a beautiful cocktail lounge downstairs near the lobby, a breakfast buffet on the second floor, a beautiful lunch and dinner restaurant named Veranda on the eighth floor, and an awesome lounge on the roof.
Book a room with a balcony, like I did, on floors seven, eight, or nine. They have stunning views of Lisbon, and you get to eat at the breakfast buffet in Veranda every morning, instead of at the one on the second floor, which was crowded.
I highly recommend staying at this hotel when visiting Lisbon. I can't wait to go back!
