Constanca's place was perfect for us. Two couples with small kids (7 & 9 month old). The apartment is bigger and more spacious than we expected, and having a separate bathroom for each family was very helpful.
We loved the location, and immediately became regulars at some of the beautiful cafes in the area (Dede's and Tiffin are both great). It was close enough for us to walk almost everywhere, but out of the middle enough to be quiet in the evenings (when the kids were asleep).
Constanca was very helpful and responsive!
