I had a more than perfect time staying at Carlos'. It was my first time staying in Rio, and the location and apartment really set the tone for a great trip. There are a ton of eateries around, including 'Santa Marta' bakery literally next door. There were minor communication problems with the guy handing over the keys (as I don't speak Portuguese) - but I was prepared already as I had translator apps in my phone. So no issues at all.
I will be back for sure...thank you!!
