Nice flat with all the equipment one might need even for a longer stay. The house itself doesn't give the best first impression but overall the neighborhood is calm and picturesque.
Nino was a great host, polite and reactive. Due to some heavy rain there was a stain on the kitchen ceiling which he disclosed with honesty, providing pictures, etc.
However, I would advise everybody to think twice before booking this flat in colder months. I visited Lisbon in January and, unfortunately, the one heater is not enough to keep a healthy temperature in the rooms... Especially the bathroom was pretty much a health hazard, even though the outside temperature was around 15 °C.
