This hostel was okay, location doesn't really matter on Ilha Grande as everything is close. We were in a 9 bed triple bunk room by ourselves, which is good because the room was small, also no wifi in it. The bathroom was pretty dirty, & the kitchen wasn't really fit for making your own meals. I guess that's because most people eat out at all the restaurants on the island. It served it's purpose as we spent all of our time exploring but if our room had been full it would've been uncomfortable.
This hostel had no atmosphere at all, only one member of staff working at any time, and only one of them could speak english the other couldn't even direct us to a cashpoint. The hostel itself was clean, big kitchen, nice sitting area and bar, if you wanted a really quiet stay it would be okay, however the area of Botafogo has nothing to really offer, you're a ten minute taxi from Copacabana but even the girl working at the desk told us she wouldn't walk the nearby streets as it isn't safe.
Lemon Spirit was a perfect hostel for the start of our backpacking trip. It was clean, the staff were friendly, good bathroom facilities and bedrooms. 2 minutes from Leblon/Ipanema beach and they organise great tours. There isn't as much nighttime atmosphere as other hostels we've stayed in and the wi-fi doesn't reach to all rooms, but those are the only two minor complaints we had.
