Hi, it depends.
A trip to the Amazonas, Pantanal or on the Estrada Real to Diamantina takes time.
You could be busy with sightseeing, nature, beach and sauna.
Have fun. If you like japanese food I can recommend Misoya Ramen (R. Antônio Carlos, N.324)
and Kome (sushi R. São Miguel, 24). Both are 6 minutes away by foot from Lagoa.
3 times i got a message and more... .
I visited the guys in their places. Mixed results but overall quite relaxing. You have to check the usual different sites, prices vary.
Some asked for european prices but you have to figure out.
I hope this short discription was helpfull.
I stayed in Cape Town in an cozy AirBNB in Green Point, visited an language school and did touristy stuff. Nice areas to stay are around table mountain and along the coast. A rental car is recommended to get around. Beautiful landscape, a lot to do and wonderful restaurants make the area a prime vacation spot. Especially with the current exchange rate.
