Marco's place was very clean and a two minute walk from the Santa Apolonia metro station. The walk from the metro station is up a hill, but very well lit at night. You could also walk into the Lisbon city centre from the apartment if you didn't want to take the metro. There's a small grocery store across the street and lots of restaurants near the apartment. The apartment is a great size for two people and had everything you needed for your stay in Lisbon.
