We stayed 1 night, needing somewhere close to Trindade Metro, being the end of the direct line from the airport, this small studio flat was just 5 minutes walk away. The area is buzzing, but felt safe to walk. The downside of this is the noise at night from revellers until the early hours, then from builders renovating opposite, and then shops opening, all is heard in the flat, even with the windows and shutters closed. The decor is clean and up to date, with a seemingly well stocked kitchenette if you want to self cater. Though only 2 coffee pods and 1 tea bag, and no sugar or milk, seemed a bit tight. There is a largish cupboard to store clothes and bags out of the main area and the shower room is newly done. The bed was clean and comfortable. But beware of exposing yourself, to the residents opposite, or workmen, if the light is on or coming out of the bathroom which has glass doors into the bedroom, or just getting up and opening the shutters in the morning, I'm not sure who was more shocked me or them.
There is a fan, as the place gets very warm (September) but it is too noisy to give a good night's sleep. So either fan noise or street noise either not great. Saying that the small studio flat is 'neat as a pin' and in a good place that I'd like more time to enjoy and explore as there seemed to be many individual interesting shops and cafes. We had breakfast in the garden of Bonjardim cafe (hard to find as it is at the very rear of a small funky hardwear/interior decor shop) which was lovely to sit in the sunshine away from the street. This was as recommended by Maria who works for Pedro.
