Nice small room in a perfect location (3 min walk to metro station, about 20 minutes walk to the center). Perfectly clean, great value for money, overall perfect to explore Lisbon. Many small shops to buy basic necessities at any time of the day also nearby, even at late hours. Shared bathroom and kitchen were very clean and mostly the use with others did not overlap, at least for me.
Mariana is also a great and very welcoming host. Would recommend, perfect for solo travelers :)
