We had a super twin room (number 8) with an unrivalled view to the palace, the river and central Lisbon. Quiet street, and woke up to happy birds chirping in the tree outside in the courtyard. Very clean, super location in Chiado. Delicious breakfast served in room. Friendly staff, historical building, amazing restaurant (Rocco) just across the road. Short walk to waterfront and shopping.
Downsides: Inflexible breakfast timings meant we had breakfast later than we would have wanted, timings are restricted and on a «first come, first serve» system which was incomprehensible. No facilities, bar the super room. It is essentially a very pleasant and upmarket Bed and Breakfast.
