Very nice appartment! The location is perfect, it is near the luis I bridge so you will have a walk with a lovely view each day. It was clean and the shower is nice (not super warm, but perfect for in the summer). The kitchen had some basic supplies to make breakfast or cook an easy meal.
There were 4 other appartments in the building, you do not share anything with other rooms and we did not hear the other guests.
Paulo and Sara were very friendly and responded quickly. The instructions for the check-in were all clear. We communicated in Portugese (which I don't speak), but with Google translate it was very easy. They also gave some recommendations for places to visit. We would definitely recommend this place.
