My wife and I (in our 60s) stayed one week at Filipa's place - a nice cozy apartment located on 2nd floor accessible by outside stairs. Be sure to learn the Tram 28 and bus system that are close by - you'll need to use them to see the sites. Rute received us - a wonderful person who gave us valuable information on things to see and where to go. A good value! We gad a great time in Lisbon.
