Beautiful apartment close to Chiado and at the lower edge of Bairro Alto which is good as this area can be active in the summer evenings. Very walkable to everywhere.
The apartment is on the 4th floor and is a steep walk-up with narrow steps, but worth it, as the view is terrific with a nice little terrace to enjoy the views. If you go in the winter, the apartment is very warm thanks to 4 minisplit heating/ cooling units. I recommend this place as a superhost.
