Apartment was lovely and clean. We arrived late but Mafalda was waiting to check us in. Apartment is in a secure location and is safe. It was our honeymoon and we were left wine and chocolates from the host. Slightly out of central lisbon but taxis are very cheap and the walk to Alfama is about 15 minutes so not far.
The host also provided us with restaurants to visit and one is very local and serves lovely food.
Would stay at this apartment again highly recommend.
