I stayed only one night but loved it! I've already been recommending this place to my friends planning to visit Lisbon.
The highlight is the terrace, I wish I could have breakfast everyday with that view. And the breakfast is 3 euros, which I think it's great.
The staff I met were always amazing, friendly and helpful. I've got lots of recommendations for visiting Lisbon in the time I had there.
The ladies and gents bathrooms are separated and that's a big plus for me.
The rooms are not too close to the kitchen or entrance area where people hang out, which made it no issue to go to sleep. And believe me, I'm a light sleeper.
Overall, a good experience.
