My girlfriend and I arrived to Rio early in the morning, and checked in at 9:00. Rafael met us in person, showed us around and the local shopping places - he is a great host, always communicated with us and helped with all the problems that we had.
The issues that we had with the place were the following:
1) the internet was not working most of the time, so we had to use a lot of our mobile data. I've tried restating the router a few times - sometimes it did work, sometimes it didn't.
2)there were two giant cockroaches in the penthouse that we had to kill. There were also very small ants in the kitchen.
3)the balcony was quite dusty, so we didn't use it a lot.
Overall it was a good stay with a few issues, and we hope these issues will be resolved in the future.
