Gardenia is a ray of sunshine that will brighten your day! You will never feel this welcome anywhere else.
The room has French doors and shutters, which allows you to either leave it open to the breakfast nook and windows or close it off to make it dark. I slept like a baby every night, which is unusual for me. There were no issues with the "bathroom schedule;" I was always able to go in there when I wanted.
The apartment is quite high up on a hill, so you will get a workout. I had a car, but after having to get a friend of Gardenia's to park it due to the extremely narrow road, I decided not to use it during my stay in Lisbon. If you are going elsewhere I would recommend renting a car when you leave the city; you won't need it and driving/parking is a pain. Get a 24 hour public transit pass and ride the trams, busses and Metro to your heart's content.
I liked the neighborhood (Graca); it's within easy access to the Miradouros and Alfama.
Would I stay again? 100%!
