The host and an apartment really great. Cassie very kind and care. The Ocean view from window is brilliant. If you want visit attraction or Lisbon you should use a car (more better than train). Also we often walked to Cascais and along the beach. In winter It is quite place for couple or family, but there is only one small playground.
The flat really white, light, good and of course cosy, something that remember a home. But in the winter it a little bit wet and not warm enough and we fixed it with air-conditioner.
If you going to Sintra please don't pass Parking (often on every sights), often there is one One-way traffic and if you miss you should go around mountain 20-25 minutes.
