I am afraid to leave a review because this is such a wonderful hidden place. In a quiet Lisboa neighborhood, in an actual neighborhood (aka no tourists). And you are close to everything! Great bars (or cafes, as they call them), great restaurants within 2 feet of the apartment, and awesome access to just about anything. A cab station 10 feet away. I don't know what else we could ask for.
The apartment is on the 3rd floor and could be a hike if you have a lot of stuff. But one of the sisters helped with a suitcase! Once you're there, it's like a small piece of heaven. Wonderful views and a great Lisboa breeze when you open the huge doors. There's a TV, fast internet, A/C if necessary, a fridge, just about anything you could ever ask for. My wife and I were not planning to stay in the room for very long, but found the place quite comfortable to relax before heading out for the night.
One last thing - the room is somewhat of an attic. Please don't expect a mansion with tons of space. It was PERFECT for a couple, no more than 2 people. We loved it and will return on our next trip.
