This is a very clean, charming apartment. It is close to a number of great restaurants in Alfama and very close to the cruise ships and to the Santa Apolónia metro and train station. (If visiting Alfama -- take the Santa Apolónia train to Lisboa Oriente to catch the bus -- very convenient; or take train from Lisboa Oriente to Santa Apolónia if coming in from airport [take red line to Liboa Oriente from airport.])
We found Inés a great hostess and she responded immediately to questions or issues. Also we had scheduled to meet her at 7:40 AM, but due to the long passport entry lines and the taxi driver having a challenge in finding the place, we didn't arrive until almost 10 AM -- but she was gracious and friendly and was accommodating throughout our stay. The stair steps are a bit narrow (from front to back of each step), and the light doesn't seem to work in the stairway passage, so good idea to carry a flashlight for coming up and down stairs -- or hold on to the railing. Once inside the apartment, it is great and all modern appliances are there. Great for a home away from home -- especially visitors that will wish to cook for part of their stay.
Important recommendation: Fernando's apartment is right next to the National Pantheon of Santa Engracia which serves as a great landmark when trying to get back to the apartment. Don't wait to see the inside of the Pantheon until later, like we did -- go see it on your first or at the beginning of your second day so you can get an overview of the entire neighborhood! Since it was so close to us, we took it a bit for granted, but it is a must visit for any visitor and especially for anyone staying in the area.
