Its a nice small apartment walking distance to most landmarks, or you can grab uber its very very affordable, not worth using public transport then you pay to 3-4 euros for the ride, we paid 9-10 euros from apartment to Jeronimo monastery, and 9-11 euros to the airport, we loved our stay there, only one thing that unit is next to some restaurants and bars, and its kind of load noises until late during night time, if you a sensitive sleeper its not for you, I put ear plugs and it was ok for me. Also AC is only in living room to keep in mind, even nights get cool, but because of noise you could not leave windows open. Everything else was perfect for our stay.
