My boyfriend and I stayed in this apartment for a week while we explored Lisbon and the surrounding attractions.
The place is a nice size for a short stay, not too big and not too small. It's also well furnished and makes for a homely and comfortable stay.
The apartment was in a nice quiet area as advertised so for those conscious of noise there is nothing to worry about. Happily though the apartment is still fairly close (20-25 mins walk) to the more raucous parts of Lisbon, Principe Real, Bairro Alto etc. The closest Metro station, Rato, is also only a 10 min walk away. It is uphill but then so is everywhere else in Lisbon. It's super handy for getting around the city!
You also have the best Ice Cream place a 5 min walk away and loads of places to get a food shop for lunches and breakfasts.
The guidebook provided was also very handy and the hosts are very welcoming and warm. It was a pleasure to stay here!
