David's place is nice and comfortable. It is about 5 to 10 mins walk from the metro station, however, u really doesn't require to take metro too often cuz david's place can easily access few important tourist spots.
David also gives us a very good briefing about Lisbon and able to offer help by using the airbnb apps always.
The only thing needs to pay attention is david's place is located at 4/F floor and the stair is quite high. My little niece earned a lot of candies after she walk up and down the stairs everyday.
