The room is exactly as described, clean and with a little balcony.
The bed was good and the rest of the apartement had all necessary things to feel confortable (fridge, washing machine...). There are 2 bathrooms in the apartment.
It is very well located in the center of Lisbon, with almost everything at a walk distance. You will be able to enjoy the night life without worrying about transportation.
I highly recommand staying there for your trip in Lisbon.
