The apartment is really close to bus and tram stop. The famous bus 28 is always overcrowded, but under the apartment there is the tram 25 that is the same and it's really more comfortable!
The station Santos is a few hundred meters, so it's easy to reach the city center, Belem or Cascais. There are lots of restaurants under the apartment and a minimarket almost always open near the church a few meters from the apartment.
I will absolutely recommend the apartment.
