If you're looking for a unique stay close to the castle in a quiet residential neighborhood, this is a cute option. The streets are quiet after tourists leave for the day.
Getting there with luggage can be a challenge. Our first taxi driver balked at going through the crowds at the castle ticket lines, and we didn't push him to keep going as we should have. Ended up walking in with our suitcases. When we left, we phoned for a taxi and thr driver came right up to our door. The location means a bit of extra walking to get to other sights and restaurants. We enjoyed a delicious meal at Claras em Castelo, right outside of the castle.
Another downside is that the floors are super thin. We could hear heavy footsteps and conversations from both sets of people (likely also short term tourists) above, which woke us from sleep when one family left early one morning. Never have heard so much noise through a floor/ceiling before!
