The apartment is located very central and perfect to discover Lisbon. Also the service and communication was really good. We asked for new batteries for the fan and got them right away.
However, this specific room is really small and has no windows at all. One night the fan didn’t work and it got really warm and sticky inside. Also the shared spaces (bathroom and kitchen) weren’t very clean. Hygiene was comparable to a Hostel.
For 1-2 nights this central location is pretty good. I wouldn’t stay so much longer in this room, since it was too small for 2 people and really hot and sticky without any windows. Maybe the other rooms of this apartment are more comfortable.
