We couldn't recommend Arno & Igor's studio enough!
We stayed in Rio for 5 weeks and several times throughout our trip we had to pause and appreciate how lucky we were to somewhat randomly end up in such a good situation! Urca is a perfect place to stay - safe, scenic, and quaint. All of the busses you may need to take come right through to the end of town and there is a Rio Bike station as well (do your research or send us a message if you want to register because it can be difficult)! Urca's location makes it perfect for easily getting to all of the must-see spots - Christo, Sugarloaf, Copa, Ipanema, Lapa, as well as the airports and bus station! Almost every night, the waterfront wall is bustling with people drinking beers, playing music, and overlooking Christo! There are A few restaurants in the neighborhood that are quite good, a nice grocery store, and most other things you might need.
The room itself is a bit small, but it's well equipped and very charming... not too mention very safe and secluded!
As for the hosts... Arno & Igor were the best we could have asked for. Helpful, responsive, and welcoming in the best of ways. We texted them almost every other day and they were always beyond happy to help out, give us information, and even get us out of a sticky situation when we lost our debit cards! Thank you so much Arno & Igor for making our time in Rio so memorable!!!
