The location of the rental is central to good eateries and access to downtown Lisbon. Don't be put off by the graffiti and vandalism that seems to be the theme all over the city.
We arrived around 1900 from PORTO via car. We waited outside the door to have the host let us in. These was no special access instructions except to wait for the host who has the key to let us in. The wait was probably around 15-20 minutes.
Please be aware that there are steps to access the elevator, so if you are not travelling light just keep in mind that you have to carry whatever you have up about 6-7 steps before you see the elevator.
The rental is spacious and great for groups like us. The main bathroom has the full sized shower and the other mini one can only fit a child or a tiny person.
Anyways, you have a nice view of the street and on days you get a good amount of light. The rental is on the 3rd floor however the street noise can be heard all the way to the bed room, poor acoustic insulations. That is not the only noise, since there is a top floor above you be prepared to deal with that as well.
Supplies are limited. We had to reuse our bath towels for the entire 5 days stay. We told Catarina about this on our departure day, she replied and said that we should had called and asked.
This was our experience.
