If you are visiting Lisbon and want a 5 star place to stay this is your room. It's well placed, near the city center by walking or public transport and easy to go to the apartment from the airport.
Besides that Céu makes you feel at home, she really took care of everything that i could need and make everything easy going. The room and the house are really well decorated and beautiful, so don't doubt and book the room.
I'll come back anytime I need and personally consider Céu a good friend that i have in Lisbon.
She deserves the 5 starts she gets.
