David was readily available when I unfortunately missed my flight to Rio. I called about midnight to notify him of the issue and he answered immediately. He is professional and pleasant to deal with.

I'll second what a previous commenter mentioned about the photos - they are touched up based on my stay in the apartment. This is not to say that the apartment is bad, just that its not as airy and bright as pictured, and could stand a little update. The couch in the living area, for instance should probably be replaced.
That said, the best thing about the apartment has to be its location in a busy but relatively quiet neighborhood in Ipanema. It is centrally located with ready transportation by bus, taxis (which run constantly in front of the building), and train (a station is a block away). Local shops, bars, restaurants and drug stores are in walking distance, as well the park which is the location of the Feria Hippie and a weekly farmer's market.
Most importantly, Ipanema beach is about 2 blocks away.

This is a great apartment that would be better with a few minor touch-ups, but I have no problems recommending it. I would definitely stay there again.
