We stayed at Marta’s airbnb for 6 months while on a work placement in Lisbon. We loved living in Graca, its a really wonderful part of Lisbon, and walking distance from the city centre. Marta was fast at responding to our messages, and quick to sort out problems like if the wifi needed topping up.
The only problems were small issues that become slightly more annoying when you are there for a longer period of time - there is no bathroom door on one of the ensuites, and no shower tray so it floods the bathroom. The electricity trips if you use too many appliances at once. And there is not enough hot water for two people to shower consecutively. The bedroom in the double bed is not a full size double either, it is also shorter than a regular bed.
However, for a short stay it would be perfect. Its also got a lovely terrace outside, and the kitchen is fairly well equipped.
