Alessandra's place is in a great location in Alfama. Close to many restaurants and bars and within walking distance of the waterfront and Praça du Commercio. You can happily wander the streets of Lisbon from here. The apartment itself is cosy and comfortable with pretty much everything you might need. We stayed for 6 nights so we took advange of the washing machine to do some laundry. We didn't cook in the apartment but the kitchen looked to be well equipped. Even though the apartment is in a very lively area we didn't really have a problem with noise. There we shutters on the windows which did a good job of blocking light and while there was some noise out in the street most nights, it wasn't crazy and it didn't bother us at all. We slept very well. The apartment has an alarm (easy to use) and there is a lockable closet in the kitchen if you have any valuables. We didn't have any concerns at all. We felt very safe.
Overall we were very happy in Lisbon and very happy with our in Alessandra's apartment.
