Overall, we had a pleasant stay. The weird part was we never met the host, we only had directions for how to enter the apartment and where to find the key.
The building is old as all are in Lisbon, so it was noisy as we could hear the slightest footstep from the neighbors above.
Kitchen and living room are smaller than what they seem from photos.
Apart for body towels, would have liked to find face towels for each person staying (there was only one for all).
On the good side, very clean, hot water, free wifi!
Location is very good, very central, close to metro, etc.
