Hello,
We had a great time at Isabel's appartement. Her son was very kind to wait for us until midnight to give us the keys after our flight was 3 hour late ! The location is great, the appartement is very clean and had everything we needed. It was perfect for us and our baby girl, would could come back during the day at the appartement so she could nap.
Lisboa is such a pretty place and we had surprisingly good weather for november month !
I would recommand staying at Isabel's place, and hope to come back some day !
