The apartment was very very nice and comfortable, really spacious, and in a terrific location. There are really good restaurants, bars and music in the neighborhood or nearby. It's right on a tram line.
Great for a couple (or two) or a small family. Misha, the host, was very welcoming and extremely helpful. Her suggestions and advice were spot on and made my trip even better than I was expecting.
The apartment is a fourth floor walk up so you will be in much better physical shape when you leave than when you arrived. And, if you've never been, you will fall in love with Lisbon.
