We stayed at Sofitel for 4 nights, overall experience is great, although this is not our first time to Lisbon but staffs are very helpful and tell us wheres the best places to go that we missed last time and also advice for nice restaurant.
Room is very dark even we turned all lights on, need some more lights, our room is facing the back of the street, got a bit of sun light in day time, not much tho. It is in fair size but I would say the shower and furnitures are bit aged, to be an international 5 stared hotel these has to be fixed.
Location is great, walkable distance to Rossio square and station. We don't like staying in the middle of Rossio since it feels a bit not secure. There is also a aerobus bus stop just opposite to the hotel, save a bit from taxi to/ from airport.
