I've stayed in Filipe apartments for 1 month period. The apartment is located in a great place Carcavelos, with 3 minute walk to the ocean's beach and 10 minute walk to the train station to the destination Lisbon or Cascais. The apartment is equipped for a monthly stay and it's really warm even on cold days. Filipe was very responsive and communicative. I recommend this place for staying, especially if you are a fan of surfing and ocean.
