Great location with an amazing view (don't be put off by the Guesthouse been near a Favela - it is safe , we walked through it several times without any issues ).
Owners are friendly and very knowledgeable about Rio and have great suggestions about what to see and do, both during the day and at night.
The Guesthouse itself is a great base from which to see Rio, there are comfortable living areas along with kitchens which make this a ideal home from home during your stay 😀.
