Shirley was very easy to contact and communicate with. Her apartment is exactly as shown in the photos so make sure you're happy with what you see e.g. the comfy bed at the top of a vertical ladder :)
Shirley is very happy to give advice and help for any travellers and before we even arrived had messaged us some information to make check-in as smooth as possible. When our flight was moved back fairly last minute, she helped us out and let us stay in the room a little longer.
The room is very close to a supermarket (Mundial), easily walkable. The view opposite the building is also very nice - of Praia de Vermelha which has a great view of Pão de Açucar.
The building has a locked gate out front with (friendly and helpful) guards watching over comings and goings which helps make you feel safe if that is a concern.
We travelled across Rio using Uber but there is a metro station just down the road from the supermarket which is convenient and taxis drive past the building frequently to be flagged down. You can also reach many places by walking if you wanted to e.g. the cable car up to Pão de Açucar.
Thanks for a lovely stay Shirley! :)
