I stayed in Bruno's apartment for one week and it was an amazing experience!! It is very well located, near everything, 4 blocks from the beach, 2 from the subway, taxis all day. Also, you have any kind of shops, coffees, supermarkets, restaurants, discos.. etc. It was the first time I was going to use AIRBNB so I had a lot of doubts, but I had not any kind of problem. Regarding Bruno, he is an excellent host!! He was kind all the time and he was always available to answer my questions, unfortunately I had not the opportunity to meet him.
In conclusion, I 100% recommend Bruno's apartment, if I had the opportunity to travel to Rio again I wouldn't doubt in staying in Bruno's apartment again.
