Rodrigo's and Diana's place is a perfect, hidden away gem. It is an easy 15 minute train ride from Lisbon that gets you out of the hustle and bustle of the city so you can have a relaxing night's rest. It's a beautiful space with access to a pool and a terrace to watch the sun go down over the ocean. It's 5 min walk from the train station and some cafes / supermarket.
Highly recommend this place if you want to be close to Lisbon but have a car and don't want to worry about it in the middle of the city. It's great access to Cascais and Sintra as well.
