If you want expansive views of the castle and river, book a room on one of the upper floors of this modern hotel. If it's summer, ask for a balcony or one of the four rooms with large terraces. The top-floor breakfast room, which has huge windows, also doubles as a bar. The staff whip up suberb cocktails, making this and the adjoining terrace a place for guests to gather for drinks at sunset or a nightcap. Though the hotel is on Lisbon's highest hill, Tram 28 runs nearby.
