Stayed with my wife and 2yr old baby, Frederico provided a nice and very useful baby crib and a baby chair !
At first, the view of the door locks in the pictures got me thinking, why such locks? is it that unsafe? (I forgot to ask Frederico about the locks, but I guess being the apartment in the top, with no neighbors and no people passing up and down would explain them) but decided to give it a chance after doing some research, mostly looking of the best location to stay / safe area, given I had big bags, stroller and a baby .
The apartment is very well equipped and clean; air conditioning and heating device. The location just cannot be beaten: nice balcony views, one block from subway, cafes and restaurants just outside, pair of blocks from food supplies, walking distance from all downtown attractions and centrally located from all other attractions in the city, quiet for a good sleep, safe for walking until late night, and so on... I just cannot describe in words how great the location is, you have to stay to understand, definitely will stay in the same place if I have the chance to visit Lisbon again.
Provided transfer from airport trough Luis, great Lisbon guide (and honest! I forgot a little bag in his car with an iPad, 2 iPhones, 2 digital cameras and my passports; he quickly came back to return it without accepting tip for it).
The first 3 levels are offices, so there are actually not much residents in the building (at least not by this entrance). Fifth floor may sound discouraging because of the stairs, but we stayed carrying the baby and the stroller up and down several times a day, so it is actually not that hard (unless you have a physical condition)...
