Anthony's apartment was in the perfect location to explore Alfama - we were within a short stroll to some of the best sights and experiences in the area, and enjoyed the little balcony over the alley. It had all of the amenities we needed and Anthony was very responsive and accommodating (his ability to accommodate self check-in was invaluable for travelers like us who can't seem to stick to a schedule).
One thing to note - if you are driving into Lisbon as we did, you will have some trouble getting to the address. Aside from the hills and narrow, winding streets (which we were prepared for and comfortable with), there are bollards blocking the road in from either end. They retract for taxis but not rental cars. And while we did get lucky to get past one, we had trouble getting out. If you can't scrap the car altogether, definitely find a garage to park BEFORE reaching the apartment. And enjoy the strolls and streetcar rides like we did!
