The apartment is clean and beautiful with great light and just as it appears in pictures. The room we stayed in (in the back) was quiet and comfortable. A crib was provided for our baby, and she slept very well in it.
The kitchen facilities don't really measure up to the rest of the apartment, and no elevator in the building means that the apartment isn't ideal for people with reduced mobility or families with strollers—but that's normal in this type of Lisbon building.
The hosts were very helpful when we locked ourselves out of the apartment (totally our own fault!), and overall we really enjoyed our stay here.
