Overall experience was good in this apartment, a neat little place for 1-2 people to stay and the host Luis responses were very quick.
As described, to get to apartment you have to walk up 3 flight of steps, I was lucky to have Luis brother to check me in and carried my heavy bag up to the apartment but I struggled when checking out, as the steps to the apartment are a bit narrow.
Walking to the water front (Cais do Sodre, also where you catch train to Sintra or Belem) takes about 20mins, where most activities are.
There is bus just around the corner to get you downtown if you not good at walking long distance.
Coming from airport will just as easy to Uber as vs. Airport bus to downtown then Uber/taxi).
The place is almost same photo tho I think photo might be taken a while ago which everything looks sharp, clean and new from reality.
