Spent a couple of nights here recently.
Firstly, my flight was delayed quite late into the evening but they stayed up to assist with directions and to open the door on arrival which I really appreciated after a stressful trip.
The location is superb, with the metro right next door allowing quick and easy access from the airport and then out into Lisbon. Everything is pretty walkable from here too I found. There are several good restaurants nearby for all meals, or there is a shopping centre directly across the road where you can shop and bring back food to cook in the kitchen.
The bedroom faces out onto a busy street, but with the window shut, the noise didn't really register. In summer, if you keep the window open for a short time in the evening to air it out, close the window and stick the fan on, you should be fine heat-wise.
Would highly recommend a stay here!
