The pictures do not do the house justice - it is on the top floor and has amazing views from all over the house...the front to the ocean and the rear to the mountains. It was super safe and the house has a doorman who is available 24 hours to let you in. There are 20+ restaurants within 3 blocks of the house you can walk to and 4 supermarkets within walking distance. No need to go to any other beaches - it was wonderful every day we were there - Copa and Ipanema might be a little busier and noisier.
A few things to any traveller about the area who hasn't been to Rio before. The house is about 30 minutes from the GIG airport (but an hour during rush hour traffic). Print the address before you leave unless you speak Portuguese and take a yellow taxi from the airport - cost about $R120 or $US35.
There is a taxi stand 3 blocks down from the house where you can get a taxi anytime. All the taxis were very helpful and reasonable. There is wifi in the house, and I'd suggest downloading google maps so you have maps at all times.
We took the bus to the Botanical garden and Sugar Loaf - both highly recommended. One way taxi to either should be no more than $R85. If you are a golfer play the Olympic course, pricy but well worth it.
Marco was an amazing host and had a bottle of wine waiting for us. Anything we needed and he had it covered. This was a trip of a lifetime and Marco's house was a big part of it. The house is super modern and has every amenity you'll need. Thanks for everything Marco.
