We stayed 4 nights at Inês place and found it very comfortable and well appointed with everything you need for a short or longer stay. It is very centrally located in Alfama which is a wonderfully traditional part of the city with lots of good food. Fado is everywhere here, so take your pick of restaurants and bars with Fado singers. It's an easy walk up to Largo das Portas do Sol for amazing views and to catch the cute yellow trams. The waterfront is also very near to here and from there you can walk or bike or scooter all the way to Belém and beyond. We walked everywhere in the city from here because that's how we like to go, but the trams and buses are also convenient. As others have said, the stairs in the building and the apartment are quite narrow and steep. Not a problem, but may take a bit of getting used to.
