The location is very convenient to metro stop (with airport access) and metro and busses to downtown Lisbon. Grocery store is just below with plenty of other conveniences nearby.
Two other rooms are also rented in this flat with one shared bath. I experienced a couple nights of people ringing the buzzer at 11pm after arriving and waking me. The buzzer doesn’t help as you contact the people through the AirBnB app to gain entry.
All said, it is good value for money in my opinion.
