Mariana is the best Airbnb host that I have ever had, hands down. I experienced a few hiccups in the first 24 hours and she went above and beyond the rectify them in addition to accommodating a few extra requests on my end.
The unit is clean, comfortable, perfectly eqipped and well located. It is 10 minutes from restaurants and shopping on a quiet, residential hill. It was the perfect retreat to come back to after a day walking around Lisbon. As a solo female traveler, I also felt safe in the space.
The only caution that I would advise (and which other reviews have noted) is that the stairs to the unit are extremely steep. Mariana had to get someone to come and assist me with my bag as I was unable to get them up or down the stairs on my own. Other than that, I would not hesitate to recommend this unit and hope to stay there again when next I am in Lisbon.
