I recommend Bernardo’s appartment for 2 to 4 people.
Pros:
- Nice, comfy and clean.
- Well located (close to Rossio).
- Bernardo’s hospitality.
- Quietness despite it’s a ground floor (entrance right from the street).
Cons
- The house was up a fairly steep slope, so it is not recommended
for people with reduced mobility. The best way to get it is from Martin Moniz Square (better than Rossio), even it’s uphill too.
