We stayed in Rio for 2 weeks at Marcelo’s. The location is great and very convenient to access the metro after only a ten minute walk down the hill. Our room was very clean and comfortable with WiFi, air conditioning, and cable provided. They even supplied a few grocery items, dishes, earplugs, clean towels, sheets, soap, etc. Any questions we had about the city, destinations, etc were quickly addressed and explained to us.
I would highly recommend staying at Marcelo’s and would also love to stay there again.
