Flat was clean, spacious and well equipped, centrally located so very convenient for seeing Lisbon. Host was friendly and check-in was easy.
Note however, the flat is on the top floor with no lifts, so it can be a bit of a trek up.
Further, for families it might be worth noting there's a strip club type establishment next to the entrance. Though this is only operating in the day, not at night, and didn't cause any problems (such as with noise or any clientele).
