When we arrived there was a giant roach in our room. I killed it, but my wife would not walk in the room without wearing shoes.
The Hotel staff also stole money out of our room. The Hotel staff knows when you enter and exit the Hotel. During our stay, we kept our money locked in the safe. Before we checked out, we packed our bags and put our money in our luggage. We put up the "Do Not Disturb" sign and went for a half hour walk. The Hotel staff observed us leave at that time. While we were out, Hotel staff entered our room without permission and stole our money. We know we had the money, because we had just counted it, for a tour the next day in Porto.
After the theft, the Lisboa Carmo Hotel Management lied to us and tried to cover-up the crime. When I first called the Hotel, the Hotel staff person Louise Silva told me that they had cameras and that I should call back the next day to speak with Hotel management to have the video reviewed to solve the crime. The next day, I spoke with Assistant Hotel Manager Rafael, who told me that the Security Manager could review the video on Monday to see who wrongfully entered our room. However, the next day, the Hotel Manager Richardo Salvador sent me an email refusing to produce the video and threatened to sue me. That was so offensive. It seems clear that Richardo Salvador was lying and covering up the theft. His refusal to produce the video is proof that Hotel staff stole our money.
My recommendation is there are lots of good hotels in Lisbon. So, stay away from the Lisboa Carmo Hotel.
