The unit was clean and comfortable, and the amenities matched the description. The location is also very central, which is convenient for getting around and seeing the sights, but unfortunately it also happens to be a very lively neighborhood which means that there is quite a bit of noise, especially at night.
The host has clearly done her best to combat this, as there are thick double-paned windows and extra wooden shutters on every window, but even with the A/C running, the windows and shutters all closed, and wearing earplugs, my family was woken up multiple times per night during our stay because people were drunkenly yelling and singing in the street outside at 12am, 1am, 2am etc.
While there were many things to like about our stay, we decided that if we return to Lisbon, we'll choose a different neighborhood, as sleep deprivation definitely detracted from the experience. If you're a deep sleeper, or plan to be out really late at night, then this place will probably be perfect for you.
