Fantastic apartment takes 20-25 minutes to walk in to Cascais. Easiest route is straight down the hill (not particularly steep) through the park to the sea front then walk along the boulevard footpath to Cascais town. However a taxi is always available and cost was 2.5-3 Euros (down load the Bolt app which is similar to Uber) and takes 5 mins for when you aren't feeling the walk. The apartment is spotless, very spacious and everything works as it should. The bed was very comfortable and we all slept well. We came for Ironman and it worked well as taxis were readily available early.
We had a great stay and would definitely return.
