The location of the apartment was great. It was near restaurants, shopping, and local attractions. It is definitely in the higher areas so be prepared to walk up and down stair/hills. But the hills are part of Lisbon's charm.
The apartment is ideal for one person. The bed is a twin (single) and as noted the shower/bathroom is small. It is located on the ground floor which is a plus particularly if you have a lot of luggage. The is no air but the windows and the Lisbon temperatures made it a comfortable stay. Having the windows open you hear all the sounds from the neighborhood. The area is not that quiet until late late evening, as there are restaurants all up and down the block. But sleep is never an issue for me.
However, I tried to reach out to Flavia and no reply as noted in the previous comments as well. I tried to messaged Flavia when I arrived in Lisbon and never received a reply. When I arrived at the apartment no one was there so I called her as she gave me her Whatsapp info. Once again she did not answer. However, a lady was walking down the street and it happened to be her mom whom Flavia said would let me in.
I ran out of toilet tissue and had to get my own as she never responded to my message that told her it was low and asked was there more in the apartment. I didn't see an iron as I need one but did not reach out to Flavia again as she had not replied to any previous messages.
