Sonia's apartment was located perfectly. A 5 min walk from the Sao Bento train and metro stations. Most of the major attractions were within walking distance. The grocery store (Mini Preco) was also only about 10 min walk and for emergencies there is a store right next to the apartment. The apartment itself was just as described and perfect for a couple or a family with children. The kitchen was functional with all the necessary gadgets and cutlery and even an espresso machine. There is a clothes washer in the kitchen.
Communication with Sonia was very smooth and we were received by her friend to help us with the checkin. Sonia was also kind enough to checkout a little late. Overall we had a fantastic stay and would highly recommend it.
