My group consisted of 4 adults and 2 kids (6 years old). We all loved Valeria's apartment because as my daughter puts it "it felt like home". I share that sentiment. Although our home is actually a medium sized house with a yard, Valeria's place had all the comforts of a cozy home (clean floors and furniture, cozy living room, comfortable beds and sheets, dependable shower, organized kitchen, wifi, and TV
Valeria's was the best part of the apartment. Although she was in the Netherlands the entire time prior and during our trip, she was always able to respond very quickly. She was also very clear with instructions. She also provided us a list of things we shouldn't miss, things Lonely Planet or Fodors didn't mention. Also, we arrived at 2:30am and we were delighted to find that she had someone stock the fridge with water and juice and bread and cheese. That was really a great convenience and a welcome surprise.
As others have mentioned, the location is great. After spending a few days in Rio, at first I thought I would have rather stayed in Ipanema, but by the end of our stay, I thought Praca do Lido where the apartment is, is where I would stay the next time I go to Rio de Janiero (the Thursday farmer's market and the proximity to both Ipanema and Centro is perfect).
When I return to Rio de Janiero, I truly hope Valeria's place will be available. She is truly an exemplary host!
