We enjoyed the neighbourood very much. It's completely safe.
It's a resiedeential area and even stairs were great to keep in good shape after the beer and the Brazilian food.
It's very close to Lapa and all the great bars for going out.
Buses are a few minutes away, so is the supermarket.
The flat is nice and cosy indeed. We felt at home. The bed is really good. the kitchen as everything you need when on vacation. It's sportless too.
And Thais is a fantastic host. She's fun, helpful and considerate. Her English is great so it was really easy to communicate.
The Friday night was a little noisy ( the windows are single-glazed)but it was the only night. So if you arrive on a Friday don't worry.
