Levy has been an incredibly helpful and friendly host. He was perfectly on time picking us up, explained everything in the flat in great detail and gave us some great sightseeing tips, for example which buses to take to the various attractions, which saved us a lot of money. We originally had some problems with the pillows, which we emailed him about and it took not even an hour for him to call us and replace the pillows the same day. He even walked us and our luggage to the hotel from which we were picked up for our onward trip and offered us to leave our luggage at his private place on our last day which would have been very helpful due to our late night flight departure.
The flat in Ipanema was very central to everything. Only minor thing to note was that it is in a short one way street, that many taxis don't bother driving into and rather drop you at the corner with the main street. Since there is a favela in the near vicinity that made us a little uncomfortable at night sometimes.
