The apartment is just as shown in the photos, and has a truly wonderful location, maybe 200 meters from the metro. Silvia is a good host, and is very helpful with providing tips and information. The cat was nice and friendly, too. :-)
The apartment is at the top of five flights of stairs, which did get a little tiresome if we forgot something and had to trek back up to get it, but that's our fault of course.
There are a lot of nice restaurants around the apartment, and it's right near the beautiful Alfama neighborhood. If people need to store luggage before or afterwards there's a store around the corner, We L You, for this purpose.
Overall we had a positive experience staying for 3 days in the apartment. Thank you Silvia!
