I visited from the United States and Ana and Pedro were great communicators. All pictures of the apartment are accurate. The apt was very clean and well appointed.
Its walking distance from the Chiado Metro stop so no need to worry about renting a car.
The bedroom is located on the back side of the building. If you use the AC unit or fan within the AC unit and shut the bedroom door you will never hear the party goers outside. You are steps away from everything the Barrio Alto/Chiado and Principe Real neighboorhoods have to offer. I highly recommend Ana and Pedro's AirBnB rental. It is a great value!
