Great host and location! Bring earplugs if you want an early night in Rio, as being on the main street near shopping Leblon cars and buses can be a bit loud until about 11pm/midnight... but if you're getting home at that time anyway then no problems.
Overall, great value for money and Márcia and her Brothers were very helpful and responsive during our stay - thank you! It's a very safe area, being across from the main shopping entrance, and only a short walk to the beach!
