The historic Solar Do Castelo is different than any other hotel in Lisbon. The rooms are quaint (if not luxurious), and the breakfast buffet offers a ton of options for hungry guests. But the real reason tourists stay at this hotel is the location; not only is it convenient to numerous sights and neighborhoods in the city, but it is the only hotel within the walls of the medieval village surrounding St. George's Castle. It's quiet, and rich in history -- the hotel has preserved a large part of the architecture, as well as adding a small museum of artifacts off of the lobby. And a real highlight is the outdoor terrace, where peacocks congregate. None of the 14 rooms are decorated the same, and some feel more upscale than others. But all offer free Wi-Fi and plenty of charm.
