The apartment was very comfortable and had everything we needed. As advertised, this apartment really is in the middle of the main Chiado shopping area, which was great for us, since that's central to everything we wanted to do and near lots of great restaurants, but it's not quiet. The windows are good and keep out most of the noise and it does get quiet at night.
Nuno lovely and super helpful for both check in and check out (and to meet us to get back into the apartment when we forgot the keys).
