Alexandra was a great host, she was awaiting us despite our delayed flight. She gave a tour showing how things works in the flat and gave advices of places near by.
The apartment was very clean and had plenty of spaces upstairs for our toddler run around. Very quiet street indeed still it's a great location. The taxi from the airport to the flat was around 14 euros.
Bear in mind that if you have a push chair prepare yourself for a lot of exercise since the street is a slope.
Definitely recommend the place for anyone visiting Lisbon.
Thanks Alex!
