Its a very nice place. The location beside the train station on the one hand and the beaches on the other was super handy, especially with young kids as it wasnt a big hassle either to get in and out of lisbon or go to the beach. Again with young kids, there is a great sandwich takeaway around the corner which we used for cheap lunches for picnics. Joana is v helpful, and there is a very good information pack in the apartment which should be read. There is a bit of street noise as mentioned by others, it wasnt a big deal for us. People in cascais were very friendly and there is a lot to do. The restaurants are good but it was also nice to stay in and cook seafood from the local market.
