I unfortunately cannot write a fair review because Sarah was not in town and left the unit to be managed by her friend who was less than pleasant, and made my friends and I a bit uncomfortable on a few occasions. I can however say that Sarah was extremely attentive and communicative, I can tell she would have otherwise been a very gracious host.
The location here is prime and the actual unit itself was not bad. The only major issue we had is that, this is the upstairs area of a much larger unit and it does not have it's own lock. So make sure to note that if you are truly looking for your own place. Other guests could have easy access to your place when you're not home. Not quite sure why this is listed as an 'entire place' on Airbnb.
Other than that, our overall experience in Rio was fantastic and again the location here was an integral part of that.
