The apartment was very good located, you can walk to many touristic places without having to take bus or metro. From the metro Sao Bento it is only 10 minutes walk, but the way is kind of difficult because it is uphill.
The apartment was very clean and for two people it is perfect. It also has a beautiful balcony where you can peacefully drink a glass of wine on the afternoon.
Only the kitchen was not so good equipped. It would be great to have at least a toaster, a kettle and new pans for better cooking, specially if you stay longer than just a weekend.
