Apartment is located on hilly area with unplanned streets. Area looked dirty to us and was definitively not suitable for babies. I would also say that the apartment itself is not suitable for babies.
The apartment floor elevation is croocked in the living room (it has a big elevation difference), electrical wires (220VAC) are installed on surface and without any proper Cable management system, which is a huge security hazard. Building sound insulation is non-existing and you can hear the footsteps and door openings all the time (terrible when someone is walking in the Building at 4am).
Apartment floor is shabby and squeaky.

As Alfama is really old neighbergood, there are no big supermarkets around so the small stores charge you with much expensive rates.
Despite, we enjoied our stay at Lisboa as the city is really nice and has a lot to offer. Our only regret is that we did not pick some other, more moderan neighbergood to stay, such as Bairro Alto, Chiado or Baixa.
Marisa offered her help on couple of occasions and she was a good host although we never met her.
