Our family had a great stay at Sandra's apartment. The best thing was the terrace upstairs, where we ate breakfast in the morning sun. All rooms are airconditioned and nice. Sandra is very welcoming and open, she gave us some good advices for grocery shopping and restaurants. If you stay in Lissabon you should take a Tuk-Tuk-Tour, it gets you into the narrow streets and to a lot of nice viele points!
