The smell was bad... room 309 (and, possibly, all of the 3rd floor of the hotel) smelled strongly of sewer gas. It is not possible they did not know about the smell, yet we were placed on that floor anyway. We endured it for the first night, then we asked for a different room because it did not go away. Room 209 (same spot in the building, but one floor lower) did not have this problem. The location was convenient for touring Baixa, Chiado and Alfama, certainly. But the price for this was double the cost of the hotel to which we moved after that, in Restauradores, near Rossio Station, which did not smell at all and was very comfortable, and was nearly as convenient to all of these places. We would have skipped Hotel 7 if we had known any of this. 3 stars are given overall, because it was convenient and the staff were wonderful, but the smell was very bad and the price was high for something that smelled so terrible.
