Marcelo is an extremely friendly and welcoming host (he even invited me to his house up the hill to use the pool and see his garden, but I did not have time!), and had no issues staying at the condo. There was enough toilet paper for the duration of my stay; had all kitchen utensils I needed (except scissors but I used a knife as a substitute); hot water; A/C; comfy bed; closet with hangers; washer. It took me less than 10 minutes to walk to/from the Glória metrô, which was essentially for me as I used it everyday. The only thing is, be careful with certain foods you keep out once you've opened them, because there were some ants - not enough to be a problem, but just be aware of it. And the closest gym is probably a 15 minute walk, but there are markets and a few places to eat close by.
This place felt like home to me, and I would love to come back when I return to Rio.
