Nuno's place was great. He was very thoughtful and gave us all the information we needed. The apartment is very good and well located, close to the Fado museum, groceries stores and nice restaurants. Near to the bus station. Alfama is a beautiful place. The only thing to be aware of is that you have some stairs to reach the building and then, the apartment. Also, Alfama has lots of stairs and "hills", so be prepared to walk in these conditions (it's worth it).
