Great location between the centre of Cascais and Gasa da Guia. The view from the apartment is beautiful and the apartment is equipped with all the things you need. The nice part about it being in a hotel is that the room is cleaned every day and the hotel reception is very friendly and will assist you in case you need information about a trip to e.g. Sintra.
Also Joanne has many good tips about where to go and what to do. She's very helpful and available by phone in case there's anything you may need.
Would definitely come back again!
