Marisa was a very good host, met me at the apartment and did a thorough walkthrough of the place and neighborhood.
The apartment is nicely furnished, clean and spacious. It is located in a mostly residential area but there are grocery stores and restaurants nearby.
You will need to walk about 12 min to get to the nearest subway station and once there, the subway is very easy to navigate while in Lisbon.
Overall, I highly recommend this apartment and Marisa as a host!
