The apartment was very close to restaurants and bars, as well as a pharmacy and a mini market. Some people have complained about the noise in the evening, but we had no issues. It is also located very close to a Metro station that makes access to and from the airport very convenient, as well as the rest of the city.
Catarina was very communicative and informative prior to the trip, and even during our stay. Her recommended restaurants, bars and things to explore/see in the city were all great.
If we return to Lisbon in the future, we will surely try to book this place again. :)
