Good location and nice historical building.
Rooms are simple but ok and some have nice city views.
Common parts are large and clean but very average and cheaply arrange with no charm at all. They don't invite you to stay for a good talk with other guests.
Honestly you can expect something else in terms of layout, equipment and decoration in such a beautiful historical palace especially in Lisbon where it is possible to find a lot of tasteful places to stay .
But Maria is a sweet and helpful guest !
