We loved our stay in this apartment. It is a beautiful apartment (as the pictures show), bright, very clean, and quiet.
It's well equipped and it even had detergent for the dishwasher and washing machine.
The area is great, as Graça is a very typical neighbourhood. There are supermarkets, coffee shops, pubs, ... at walking distance. It's also very close to Miradouro da Graça and to Miradouro da Senhora do Monte (with an even better view of Lisbon). The famous tram 28 stops just a few minutes away.
The check-in process was a bit bureaucratic, but I guess this is for safety reasons. After making the reservation I had to send a selfie, a picture of my ID, and a covid negative test (this is part of the new legislation in place). The key is in a lockbox easily accessed, but the PIN was in an external website (from the company that manages the stays), instead of being in the Airbnb app (in the check-in process).
The contact (24/7) is through an agency.
