Teresa was a fantastic host who did everything she could to make sure we enjoyed our stay (including surprising us with cake). Teresa, and her son Pedro, met us at the apartment in the early hours of the morning to let us in and provide us with a detailed tour of the property as well as giving plenty of suggestions of sights to see, restaurants to eat at, and bars to drink in.
The property itself is very clean and nicely decorated with lots of cooking equipment available if you don't fancy spending lots of money eating out (there are a number of mini supermarkets within walking distance).
I would happily return to this property should I visit Lisbon again.
