I want to start out by saying Miguel was always very responsive, and went out of his way to provide us with a pleasant stay. There were a couple hitches, and he was always ready to help. On the first day, his sister Rita welcomed us with lots of tips from the city.
The apartment definitely looks like the pictures, but keep in mind the only windows are the one you see by the door, and a ceiling one in the bedroom. There's plenty of artificial light, but it's pretty much dark inside regardless of how sunny it is outside. It felt stuffy and in the first couple days I was a bit sick, but we kept the windows cracked and that helped. Again, Miguel was prompt and offered to move us but we decided to stay.
It's a fine place, otherwise. Fully-equipped, recently remodeled; the neighborhood is very central, walking distance to pretty much everything you'll want to see in Lisbon.
