We had a very positive experience with Natascha and her apartment. She was a very good host, organized and had everything clean and ready for us by the time we arrived, as well as personally welcoming us. Moreover, she also helped with handy local advice, much appreciated.
The apartment delivered exactly on its promises, no overselling from the ad, everything was as announced. The location is amazing. Right by the action in Lapa without being in the middle of it, so surprisingly quiet for where it is. Connectivity by bus is also convenient.
Overall I highly recommend staying in Natascha' apartment! What a relief after the many rip-off and low quality hotels one has to contend with in Rio.
