Four of us (2 couples) shared Alessandra's apartment for 10 days and had a great stay. Check in was easy by collecting the key from the 24 hour doorman. The apartment can be reached via the lift or 2 flights of stairs, the stairs are very steep though so not suitable for everyone.
The apartment was exactly as shown in the pictures. There is one large bedroom and one smaller bedroom. Both have double beds, wardrobes and air conditioning. There are 2 bathrooms, 1 opposite the larger bedroom and one off the kitchen.
The lounge/kitchen area was a nice size with everything that was needed. In the lounge area there is a nice tv with cable and the kitchen has a fridge/freezer, dining table, storage shelves, cups/glasses and enough cooking utensils to prepare your own meals if you wanted to. There is also a washing machine and drying rack if you are planning a long stay.
The location is perfect with a small shop next door for essentials, a supermarket 5 minutes away and plenty of restaurants around to satisfy most people. Copacabana beach is 1 block away and is reached within 5 to 10 mins walking.
We did have a couple of minor issues whilst in the apartment with one toilet and one of the air conditioners but Alessandra had both problems fixed immediately and was always available should we have needed anything else.
Overall we would all highly recommend Alessandra's apartment for your stay in Rio.
