Beautiful apartment, fantastic views (from the terrace and the sunroom). Monte Estoril is also a very nice city. Walking along the shore was our favorite. The drive to Lisbon is quick (20-30 min). We didn't experience the train but the station was only at a 10-minute walk. Nearby, there is a cute park with a kids playground, cafés...
The apartment itself was lovely, nothing bad to say about it except for the strong chimney smell (CO emanations) in the evening (when a neighbor would use it). When you have young children, this could be a concern.
Beds are comfortable. Kitchen is well equipped.
We totally recommend Tracey's place and thank Cassie for the nice check in experience.
