Very cute, it's like a small hostel with private rooms. Close to Bairro Alto, Bus and old tram station in front of the house, awesome view over Lisbon, you even can see the beautiful bridge, very beautiful at night :)
Be careful: the rooms are in the 5th floor and there is no parking lot in front of the house, but a car park 10min by foot called Av. Brasilia. It's just 3€ from 9am to 7pm(?), so you can park there 2 nights for 3€ if you arrive late and leave early.
Would definitely recommend it!
Thank you very much :)
