We travel with two young children (3 and 5 years olds). The appartment was really appropriate for a family. It was modern, pretty clean, large enough and well equipped (even some toys and kids book). The huge advantage of this appartement is his location. Near all the the attractions of Sintra. The appartement is located over a restaurant (by the way a very good one). Some comments talked about the noise. In our case in didn't bother us so much ( the kids includes).
