We really enjoyed our stay in this apartment. The view from the balcony is spectacular, many tourists come to see this view near the cathedral, but you have it right there in your balcony!
The apartment is very clean and they provide us with everything you will need.
The location is perfect. You can walk there from Sao Bento train station. To do it just walk to the Cathedral and pass it to the end of it and you will find the apartment easily.
We came with my mother in law who is 74 years old and had no issues walking up the stairs or walking in the city.
I would come back there again, and would highly recommend this place.
