This apartment is perfectly located. The neighborhood Alfama ist very beautiful and so alive. You can reach city center, shopping streets as well as other tourist attractions in a 10 to 15 minutes walk. Nearby you have a lot of small shops and restaurants, plus a trainstation if you plan to make a longer trip. The view from the apartment is beautiful and the terrace in front is amazing, probably my favorite place in Lisbon.
Overall I can really recommend this place! And Fernando is a very nice person.
