Location, location, location. For the record, this is my 3rd trip to Rio and I've stayed in more than 5 different hotels and airbnbs across all the trips, so I feel fairly familiar with the city. This place is a few minutes walk from the beach, in addition to minutes away from many bars, restaurants, and grocery stores-- I think there are at least 4 grocery stores within 10 minutes, and one of them is organic.
There's plenty of natural sunlight in the place, which I love especially in the mornings. The washer and A/C weren't working there, but we already knew that before booking so that was quite courteous of Ana to let us know in advance!
It was just my girlfriend and I and the space was plenty for two people, not crowded one bit and absolutely spacious.
