The Heart of Alfama has an excellent location. It is covenient to downtown, Alfama, Chaido, and all the areas a visitor to Lisbon would want to experience. The studio apartment is well decorated and the entire building is modern. If you use Uber, keep in mind that they are prohibited from entering the neighborhood, so be prepared to walk down the the hill to the Main Street to grab your ride.
The neighborhood is typical of rapidly gentrifying communities, dirty, under construction and old timers weary of frequent and changing visitors but they are not hostile.
It was a nice place to come home to after a day of hard touring.
