Pros:
1. Amazing view, probably the best I've ever seen in Rio.
2. Great location for fast trips (you can just walk to Santos Dumont airport) and you are just at 10 minutes walk to Lapa.
3. 4 bathrooms is great for big groups (we were 6)
Cons:
1. In order to make you save energy, you need to pay for it. It makes sense so that people avoid leaving the A/C or TVs on. But I would suggest that there was a tolerance consumption for smart guests like us to avoid needing to exchange dollars to pay just a 5 reales energy consumption. (For example, you could have a tolerance of 3 reales per day)
2. The matres on the main room (the one with the best view) is old and uncomfortable.
3. There is a sewage smell inside and close to the bathrooms
All that said, I would go back if I have a fast trip of 2/3 days in Rio and I'm not in the mood for beach baths.
If you want to swim in the beach I recommend staying around Ipanema or even go south to Barra de Tijuca; that's another Rio experience out of several you can do.
