Sofia's apartment is very well located, at a walking distance from the Alfama and the Bairro Alto districts and close to the Metro and the Rossio train station.
The apartment is small but very nice and very well equipped (we really appreciated the coffee machine :) ).
During our staying there were some renovation works close by (long term ones, so expect them also in the next months) and there was some noise in the morning after 8 am (but not on the Good Friday and the weekend) and one evening (but the last one was probably an emergency).
We liked the apartment, although it needed a couple of fix, already planned by Sofia for April, so everything should be fine by then.
