We have stayed 3 nights with 2 kids in the apartment.
Lupin the host was quick to response and greeted us when we arrived.
There was a very bad smell issue in the apartment that came from the bathroom (a smell that seems to be coming from the sewerage). Although Lupin was very responsive and tried to solve the problem it was not solved.
In addition there's some power outlets problem that we couldn't use.
The kitchen is really well equipped and made it easy making dinners and breakfast for the kids.
Having a parking space is an advantage in Lisbon since you don't need to use the car while traveling.
