We really loved our experience staying here. It was our first time to Brazil and we could not have picked a better place. The apartment is modern and clean and well equipped with en suite plus fridge and microwave. The apartment block is very swoosh with 24 hour reception and doorman, and the location is good too. It felt very safe and has excellent transport links on bus and metro within 2-5 minute walk, plus tourist information office is just 200 meters away. This is a very private space, just like a hotel room with maid service to come and clean each day. Downstairs is a place for buffet breakfast for ~$4.
Dumont and Sandra were very helpful too, keeping in touch with email with lots of great advice. It felt like home from home and we would definitely stay here again if we came back to Rio.
