So, we had the best stay via airbnb in Ricardo's flat so far! The flat is obviously super cool with unique and personal interior. Ricardo is a very helpful host, always available for any requests! He even ordered us a taxi.
The neighbourhood is alright, it's really close to Lappa, one if the best places to go out in Rio and not as touristic as copacabana for example.
The only downside was the cold weather, cause it's more like an 'balcony-apartment' than a closed flat. So I would recommend to stay there in summer, but we had enough blankets, so everything was fine!
The flat is also very close to the next bus and metro station, from where you can get easily to ipanema or copacabana.
Thank you, Ricardo and a big recommendation to everyone who wants to stay in Rio!
