The pictures of the apartament are puting it in a brighter light. Location is quite good, 10 min walk from downtown. The apartment is spacious but was a bit smelly. The bed is in a small room with little space to pass around it.
Worse part was the noise from the apartment above. You can hear everything because there is no sound insulation.
Overall the stay was ok but I would choose something else for my next trip to Lisbon.
