Juliana was very responsive and timely in her communications. She insured we had all of the information we needed to get to the apartment, that everything was ready for us and that we felt welcome. Juliana is an excellent host and true to her word in all aspects. Our only issue with this apartment was that, while listed as "air conditioned," only one of the bedrooms had an air conditioner in it. In that room, we were quite comfortable. The rest of the apartment - and especially the other bedroom, were unbearably hot. Given we were there in the hottest part of the year, it would have been preferable to either have working air in the entire apartment or at least in both bedrooms. The other couple travelling with us were so miserable they had to find a hotel room.
That said, the apartment is very well situated on a nice street within just a few blocks from Copacabana beach and we would us it again if it were just my wife and me. If you're travelling with others (friends, family, etc), be aware that only one bedroom will be cool....
