Marcos and his parents will make you feel like home, or even better, you will experience a real Brazilian home.
Regarding the room, it's perfect to rest with a very comfortable bed. The location es very strategic, only two stops close to the airport, located at the red metro line which also connects you to Lisbon's centre. It's very easy and cheap to move around Lisbon. It's also close to Estação do Oriente, where you have Lisbon's train station, the bus terminal and a huge shopping mall called Vasco de Gama. It's literally only a 10 min walk away.
A 10/10 experience. Obrigado.
