We were looking for a place close to the airport, and found Connie's place. Connie' place was about an 10 min drive from the airport. It was about a 10 euro Uber ride from Alfama, where we had dinner.
The place is clean and comfortable, and was exactly what we were looking for in our last night before our flight home. It was great that the apartment had its own parking space because parking in Lisbon is challenging.
Our only issue was that the person sent to help us check-in was late, but there might have been traffic issues that caused his tardiness. It would not have been as much of an issue but for the fact that we had two young kids who were tired and cranky after a 4 hour drive.
