Overall we can't recommend Pascal's place.
As with everything in the neighborhood, the building is old, and includes some tough old-building features, such as very small stairways with obstacles to duck and avoid. The upstairs bedroom is a loft, with such a low ceiling that requires ducking at all but its very center. While having two bathrooms is nice, both are extremely small, barely allowing one to stand outside the shower.
Pascal's arrangement of the place could also be improved. There is no living room or space, and no seating other than at the small dining room table. We'd recommend converting one of the bedrooms to have a sofa or convertible bed.
While the Alfama neighborhood has plenty of character, it also has its downsides. Other than its plentiful Fado restaurants, there is not much nearby commerce (coffee shops, grocery stores, etc.) The cobblestone streets are steep, and quite slick when wet (which they were quite often). We also had a hard time with a few of the neighbors. It was quite loud at night, including a barking dog and music at 4am. We had a few nights where it was difficult to sleep.
Last, we found Pascal's place lacking in attention to detail. Kitchen supplies were quite sparse; we couldn't cook more than the most basic meals. (Example: lack of cutting board.) There was no toilet paper when we arrived, so we had to rush out in a bit of an emergency.
