This was a very cute place. It's not a private space really, as you do need to go through the common area of the owner's apartment to get to this rooftop apartment and there is no door that closes off the main part of the roof (kitchen and jacuzzi) from the owner's apartment but there is a door on the bedroom/bathroom that makes that space private. I think the listing should be updated as a semi shared space and not listed as a whole private apartment.
The view of the Christ the Redeemer statue from the jacuzzi is really nice. The kitchen is very small, and doesn't have great appliances, so be warned if you are planning on cooking here. The bed is not the most comfortable, I think it needs to be replaced (it's not terrible but don't expect a luxury sleep as the bed has a bit of a dip in the middle and not much support for your body).
The water pressure in the shower and sink is really good. The kitchen sink has a filter which was great and the host had 3 bottles of water ready upon arrival. There was soap for hand washing, showering and dishes which was good (I've stayed at some Airbnbs that didn't have hand soap - this was not the case here). The internet speed was good enough for all my Zoom meetings and live streaming I needed for work.
The jacuzzi was pretty nice, not a luxurious jacuzzi, but good for an outdoor nature feel.
All in all, I think this place is a nice for a short romantic stay. In my opinion, not ideal for long term stays or those who work from home all day and cook most meals at the apartment. I paid a lower rate for Airbnbs in Rio that had 2 bedrooms, 2 bathrooms, were completely private, had amazing kitchens and clothes washers. So I think the price is a little high for the overall experience but I definitely don't regret staying here. Great location, memorable experience.
