I really enjoyed the the stay at Beths home. It was a very nice and clean space. In the night it was quiet so that you can relax. Close to the house were we stayed was a small super market (10 mtrs.) 30 mtrs. away a policy station. We fellt very safe.
In Santa Teresa you have a lot of possibilities to spend the night, bars (with live music e.g. jazz, house), restaurants, cinema small brasilian shops.

I can definitely suggest to go to Beths place and enjoy Santa Teresa.
