We had a great stay at Sofias apartment!
It is a really spacious and beautifully decorated flat with everything in it that one might need. Towels and sheets, as well as a hair dryer and kitchen necessities (such as spices, pans, pots and everything else) are being provided. We even got some Pasteis de nata as a welcoming gift, wich was a really nice gesture!
It is true that you can hear the neighbours moving around quiet a lot but that's normal for old buildings in Lissabon like the one Sofias apartment is in. One thing that we did not know before staying in the apartment (maybe because I just didn't read carefully enough) is that it is on ground level, meaning that if you open the windows of the bedroom, you're looking directly on the street. That's why we kept the shutters closed all the time. Didn't bother us much but might be inconvinient for someone else.
Anyways, I really recommend this apartment not just because of it's interieur but also because of it's location (quiet neighbourhood).
