The cleaning standards of the apartment were very low. We found hair from previous guests and dust in the drawers (some of them were very old to function well). In the sink in the kitchen were food left from others and the bathroom was not appropriately cleaned. There are 2 bedrooms in the apartment, the one is very comfortable and has a light and decent matress. The second, though, is very dark and we could feel the springs of the mattress. It was very inconvenient to sleep there. Also, keep in mind the walls between the rooms and the living room are very thin, you can even listen to the other people changing positions when sleeping...you don't feel like there's privacy at all. We communicated some of the difficulties to the host and he kind of gaslighted us and did not show any willingness to improve our stay. Also, there is no balcony in the apartment and only windows to the back of the building's side. We cound not cook because you can only use one stove from the kitchen due to low electricity capacity of the area (as the host explained). The apartment is very expensive for the facilities it offers.
On a positive note, you can enter the building and the apartment with passwords, so no worries of losing a key or coordinating with your travel buddies on how to enter etc. Alfama is a cute neighboorhood and close to many central areas. Though, if you want to eat somewhere less touristic its not easy at all in the neighborhood.
