Our stay at Silvia's apartment was very pleasent. We are a family of four adults that went for the Olympic games, so it was slightly crowded for us, with only one shower. However, the apartment was very well located and it was really easy to access the subway and get around Rio and all its sports venues. Also, it was surrounded by different restaurants, so we didn't have to look long for a place that we liked with so many options.
The furniture was a bit dated, and we had a bit of trouble with the bathroom door, but it was all very clean and we had all the supplies we needed.
Overall, it was a good stay and we would definetely recommend the place.
