We stayed at Sandra's wonderful flat for 6 days. It is beautifully located in the heart of old Lisbon. Train, grocery, restaurants and lots of sights are all with in five minutes walking distance. The place is loaded with everything you need, spotless clean and the bed was so comfortable. It is stocked with local information and guide books in multiple languages.
We never met Sandra, but her mother met us on check in, and was very helpful and full of energy. She did not speak much English( which is fine), but was fluent in French, which worked well for us. I can't say enough good things about this place. We would recommend this flat and we would stay over and over again anytime we are in Lisbon.
