We thoroughly enjoyed our stay, the location is great if you want to enjoy the old town Lisbon experience. Many many restaurants nearby. The apartment was large and comfortable. Being on the 4th floor, the elevator was much appreciated.
The apartment is on Rua Augusta which is where the action is, so there was some music and street noise in the evening. However the apartment is quite soundproof so that was not an issue (just added to the ambiance).
We would rebook this apartment on in the future.
