Our stay in the Bairro Alto neighborhood was fantastic thanks in large part to the AirBnB and hosts! First off, the location is perfect. It is within walking distance to nearly all the attractions of central Lisbon or public transportation that can bring you to where you want to go. The neighborhood is filled with restaurants, bars, and other entertainment. The apartment is directly above a fado bar, so it can get noisy at night from dinner to close, but why are you in the AirBnB during those times?
We weren't - so we didn't have any issues. The space is clean, organized, comfortable, and honestly felt like home. The patio area is lovely for a morning coffee. We used the space as "digital nomads" for a few days and then strictly vacation for the rest of the week. We would highly recommend to anyone for either purpose! Side note: My wife sprained her ankle and the hosts helped find a crutch at a local pharmacy! They were super responsive and so helpful. 5 stars!
