Nunos Airbnb is extremely well located. You find the tram (famous 28), bus and metro just around the corner. There are laundry shops nearby and a few very good restaurants as well. For grocery shopping there's Lidl close by.
I spent five weeks in the Airbnb and worked during the morning/early afternoon and I can definitely recommend the flat for that purpose. Since it's located in a backyard you won't have the noises from the street and the wifi is extremely fast and stable.
The communication with Nuno was also great. I can't recommend this Airbnb enough. Will definitely opt for it again when I'm in Lisbon.
