I was in Lisbon for a conference at the university. Armando's apartment was perfect. It's just 10min walking from the campus. Around there are many little shops if you need something, and it is less than 30min by subway to visit touristic areas. It is only 10min taxi from the airport. You can hear the aircraft from the apartment, but if you are used to city noise, it shouldn't be a problem. The apartment looks better than what is on the pictures. It's beautiful and you can admire the artistic creation of Armando's wife. She is talented. Armando spent lots of time explaining me the area, helping me with my question, and he even helped me with booking a taxi to go back to the airport. I wish I weren't so busy by the conference, we could have spend more time chating. The Carvalho family is very nice.
