I think the place is the epitome of attention to detail. Very stylish, great lighting for all moods, each room in the house was very well designed. I'd say it lacked nothing for
modern convenience and comfort. And I lived here for about 3 weeks.
The only gripe I had was there is a building in front of it, but that only last a couple of days and it's 2 minutes walk from the best views in the city both uphill (The mira-doro's) and downhill the Ports and Lisbon River.
On the stairs - the stars to the building are not much more than you would expect in Lisbon, it's a hilly city in general.
